Product Warning

I’m passing this along on an ‘off’ day for the blog because I feel that it’s important to share this info . The EPA has issued a statement concerning the danger of certain flea control products to children that come into contact with them.

An Environmental Protection Agency report warns that propoxur, a flea-killing chemical in flea collars marketed by Sergeant’s Pet Care Products and Wellmark International, is unsafe for children. However, the products can be distributed until two years from now, and retailers can continue to sell them after that until their stock is gone. Veterinary dermatologist Daniel Morris says there are safer products available and urges owners to consult with their veterinarian to determine the best approach.

There’s a more detailed article at this link.

I’ll leave it to you, readers, to decide how you feel about it. Sound off in the comments! I’d like to hear what you think.

A Quick Bite

A Quick Bite

The news was somewhat boring today, so I’ll throw out a few facts to jog your memory about flea control. We’re expecting an intense number of fleas this fall. Hot, humid weather allows them to breed in the shortest possible time. Flea prevention strategies are more important than ever!

A female flea can lay 50 eggs a day. By the end of one week, a single female flea has created 350 offspring.

Fleas can go from eggs to adults in as little as 21 days.

Immature fleas can lay dormant in a pupal (cocoon) stage for as long as a year before hatching.

So, if you’re seeing even a single flea on your pet, you need to assume a few things right away:
1. You didn’t see anywhere near the full number on the pet.
2. You haven’t seen the much higher numbers of eggs and larva in the environment.
3. Things will get worse before they get better as those eggs mature into new adult fleas, even if you kill the current adults.

Topical parasite prevention is the -best- way to protect your pets from bringing these nasty parasites into your home to begin with. Treating the house with a premise spray is a critical part of breaking the flea’s life cycle. Products provided by your veterinarian, guaranteed by the manufacturer, are your best bet for prevention and treatment.

Guest Blog – Stray Cat Adoptions

Winter made its presence certain today when we woke up to some snow on the ground. Whenever the weather turns cold like this, I wonder what happens to all of the stray cats and dogs that have been outside since the summertime. I always hope that someone will be able to take them in so they don’t suffer from exposure to the weather or starvation. It’s a rough time of year.

We frequently see stray cats that are brought in for the winter. Most of the time, clients have the best intentions and I certainly applaud their generosity in opening their homes, hearts, and wallets for these ragtag pets. There are a few dangers that I wish clients knew about ahead of time, especially if there are already cats in the house.

This week’s post was written by Diane, one of our LVTs. She will touch on a few of the concerns we have when taking in a new cat.


A gentleman was in the hospital with his dog recently, and mentioned that he got a cat. I said, “Oh, where did you get him?” He responded that the cat wandered to his house, and the man decided to keep him. The gentleman commented, “We figured he’s been around a while outside and is still alive, so he must be healthy because he hasn’t died from anything yet, right?” I shuddered and my mind raced with all of the possible diseases and problems I needed to warn him about. I gathered some informational brochures and started the conversation.

I started with zoonotic diseases, which are diseases that can be transmitted from animals to humans. Rabies is by far the most important and deadly disease, but not the most common, and is transmitted by a bite from an infected animal. Intestinal parasites carried by animals must be addressed first. Roundworms, hookworms, and toxoplasmosis are all parasitic diseases that are spread to humans by contact with cat feces in soil or cat littler. Cat Scratch Fever is a flea-borne infection typically transmitted by a cat’s scratch or bite. A stool sample to check for intestinal parasites is the best way to find out what a cat may be carrying inside.

The next topic of conversation was about two viral diseases that the new cat could be carrying without any signs. Feline Immunodeficiency Virus (FIV) and Feline Leukemia (FeLV) are diseases in cats found in every region of the country. Each is highly contagious fro cat to cat. They can be fatal infections. Both have few outward signs initially, and no “sure” signs. [Dr.H adds: when a sign of disease is 100% certain to be from that disease, we call it a pathognomonic sign. FIV and FeLV don’t have pathognomonic signs.]

These viral diseases are associated with illness and death of more cats than any other disease. The viruses work by weakening a cat’s immune system. Without testing, there is no way to know whether the cat is infected. Without a diagnosis, the cat cannot be treated properly. In some cats, signs don’t appear for weeks, months, or even years after they are infected. Testing is important so we know whether a cat is carrying these diseases.

Infected cats can show vomiting, diarrhea, weight loss, weakness, fever, pale gums, dull or matted hair coat, swollen lymph nodes, mouth sores, or behavior changes. If the cat has been living outside for months or years, a new owner might not be aware of these sometimes subtle changes.

[Dr.H adds: Upper respiratory diseases, fleas/ticks, and ear mites are also very common problems seen in stray or orphan cats. While these problems aren’t generally life-threatening, they can be a serious headache for a new owner. These problems are highly contagious and rapidly spread to other cats in the household. Fleas and ticks are also a risk to humans. Vaccination and treating external parasites are a critical part of a “new stray cat” vet visit.]

If a person wants to bring in a stray, it’s imperative that the cat is examined and tested before coming into contact with people or other pets. Testing, vaccinating, and deworming should be performed, and a quarantine period may be appropriate, too.

I thanked the client for his willingness to give a stray cat a permanent home, but also tried to show him the risks a cat with an unknown history can bring. A full health check with the veterinarian is the first step to providing a loving, caring home.


Diane’s focus on the viral diseases is very appropriate. I counsel all owners of newly acquired cats to allow us to perform the simple blood test that can detect FIV and FeLV. Results are available within 10 minutes right in the hospital, and the test is quite sensitive. There are some nitpicky concerns with the age of testing for FIV, but FeLV can be tested for at *any* age.

I feel that knowing the viral status of new cats is the most important first step. These diseases will shorten a cat’s life considerably. While some owners are able to take in a cat that is positive for one/both of these infections, some owners don’t want to put their other cats at risk. In a rescue situation, the resources that will be spent on a cat with a generally fatal viral infection could be used to rescue several other healthy cats. It’s a very sticky situation wrapped up in ethics and harsh realities. Ultimately, as each owner or rescue group makes a decision about how to handle these cats, one thing is clear: it’s better to know what you’re dealing with. Testing is step one!

Please ask questions. We’ve brushed the surface of adopting a new cat, so I know there must be some things that you’d like us to go over in more detail. Thanks for reading!

Tech Guest Blog : Fleas, Fleas, Fleas

Today’s topic was written by Jenn, our senior tech. The weather’s getting colder, but the fleas aren’t finished yet. We’ve seen a TON of cases, so Jenn wanted to review how we tackle a flea problem. -Dr.H

Fleas, fleas, and more fleas! That seems to be the trend this time of year. We always recommend preventing a flea infestation from happening by keeping pets on a topical foe preventative all year long. Once your pet has fleas, it can be an uphill battle to get rid of them.

A flea infestation usually begins 6-8 weeks prior to the first flea you notice on your pet. By the time fleas are seen, there can be thousands of flea eggs, larva, and pupae in your household. If you have multiple pets, the numbers dramatically increase. There is no magical medication that can kill the whole flea population or infestation in an instant. It will take three to six months to rid your home of an infestation.

The first step in controlling an infestation is to apply topical flea preventative on your pets. Select a product that is applied to the pet’s skin, not just on the fur. Also be sure to choose a dog product for dogs and a cat product for cats. Some dog products can be dangerous if applied to cats! Once the product is applied, any adult fleas on your pet will be killed within 12 hours and the flea’s life cycle has been interrupted.

However, there is a whole population of immature fleas hiding in your home while they mature into new adult fleas. It can take as little as 21 days for them to grow into adult fleas after hatching from an egg. These fleas will appear on your pet, which may seem like the product isn’t working. You may even see more fleas on your pet than before. The topical prevention will kill these fleas before they have a chance to bite your dog and reproduce. This begins to reduce the size of the infestation in your home.

As long as the pet is on a topical flea preventative consistently, applied every 30 days, the product will stop flea reproduction and control an infestation in about 2-3 months. Severe infestations may take longer to fully destroy.

You can help reduce the population in the home environment by taking some specific steps. All furniture should be vacuumed. All floors (carpet or wood) should be vacuumed. Throw the vacuum bag away after vacuuming. All linens and anything pets sleep on should be washed in the laundry if possible. Treating the house with a flea spray will also help kill fleas in the environment. Be sure to follow the directions on the product!

In summary, here are the key points to remember when dealing with a flea infestation:

All pets in the household must be on topical prevention
Prevention must be applied every 30 days
You will still see fleas on your pet, but they are on their way to being dead
It can take 3-6 months to fully control an infestation
Environmental control is also very important

And most importantly: It only takes ONE flea to start an infestation! Prevention is always better than treatment.
