Cat Allergies to Flea Medicine
tdzyk posted:
My 2 1/2 yr old cat had a terrible allergic reaction to Revolution a year ago. My vet switched us to Front Line and after a year, my cat had the same bad reaction. Now the vet is recommending a pill for fleas but it does nothing for ticks or mosquitos so we would have to watch for them manually. Our cat is a house cat, but LOVES to go for daily walks on his leash which is why we're concerned about ticks and mosquitoes as well as the fleas.
I've heard that there's one more flea/tick medication out there called Advantage. Does anyone know if this is good/bad/comparable to Revolution and/or Front Line?
kittykatjenn responded:
Sounds like you should stick with the pills and leave it at that. Do you walk your kitty in tall grass or wooded areas? I have a kitty that is allergic to all that stuff too. She doesn't go outside though.
Violets_are_Blue responded:
You can try Advantage and see if works for her. However, a couple of questions should be asked regarding the sudden reaction. Is it localized to where you apply the Frontline? Does it appear within 48 hours of application and no other possible allergen has come up?

Frontline also does not protect against mosquitoes but her being on a heartworm preventative is a good idea. There are oral heartworm preventatives for cats (Heartgard Chewables and Interceptor tablets). You can try Advantage and see if it works but, if it causes a reaction, it would be best to stick with oral pills/
Drew Weigner, DVM, ABVP responded:
Yes, Advantage is a topical flea preventative that most cats tolerate well. But considering your cat's history, I'd use an oral medication for fleas. No product prevents mosquito bites but you're probably thinking of preventing Heartworms, which are transmitted by mosquitoes, and there is also an oral Heartworm Preventive for cats.

Ticks are another matter entirely. Since they're big enough to see, you could just comb and examine your cat after going outside and remove whatever ticks you see. There are also flea and tick collars that can be effective, but you'll need to ask your veterinarian if this is safe with the oral flea medication he's recommending.
