We are recommending that our cat owners use one of the topical flea preventatives: Advantage or Frontline, also known as TopSpot. Advantage kills fleas within 24 hours and continues to work for 4 weeks. (*The canine product, Advantix, is very toxic to cats.) Frontline for Cats kills ticks and fleas and is often used on the indoor-outdoor kitties. Both products are topical liquids, which are very safe and available from your Veterinarian. Again, never use products intended for dogs on your cat.

FRONTLINE Plus is a convenient once-a-month topical product offering the longest-lasting, most complete protection against adult fleas, flea eggs and larvae, and all four major species of ticks. FRONTLINE Top Spot provides fast-acting, long-lasting flea and tick control for cats. Ask your veterinarian which FRONTLINE product is the best choice for your cat.

It's not unusual to see fleas for about 2-3 weeks after you've begun treating. This is because some fleas that were already developing in the pupal stage when you started to treat will emerge from their protective cocoons. These pupal or "cocoon" fleas, which can survive treatment with any product, take about 1 to 2 weeks to develop before emerging as adults.

For best results, we recommend that you vacuum right before any home treatment, and frequently between treatments. The heat and vibration from the vacuum will stimulate adult fleas to emerge from pupal cocoons so they can be quickly killed when exposed to the treated carpeting. If you are still seeing fleas after your first home treatment, we recommend vacuuming every day if possible, or every other day, for about 2 weeks.

We know that the levels of cat allergen drop quickly once the cat is removed from the home, but unfortunately the allergen level can remain in moderate quantity for up to six months. In addition, cat allergen can remain in a mattress (where the cat has laid) for years.

Flea eggs can stay dormant until the conditions are right for hatching. Humans can easily transfer them on their clothes and shoes. Prevention is the best course of action. Consult with our veterinary staff for the most effective course of treatment.

Hedgehog fleas are host specific, which means they will not usually live on any animal other than a hedgehog. Not all hedgehogs have fleas.

Fleas are a problem that should be taken seriously. These tiny parasites feed off of your pet, transmit tapeworms and irritate the skin. Carefully check your cat once a week for fleas and ticks. If there are fleas on your cat, there will be fleas in your house. You may need to use flea bombs or premise-control sprays, and treat all animals in your house. Make sure that any sprays, powders or shampoos you use are safe for cats and that all products are compatible if used together.
