Can Cats Have Adverse Reactions To Frontline Plus?

Recently I used Frontline Plus for Fleas, Ticks, and Chewing Lice. Tigger, my seven year old, became very lethargic, avoided noise and light, and refused to eat for days. He was once too weak to get into the litterbox, wetting the bathroom rug. He's NEVER done that before. He didn't seem to really know where he was. He is better today. Has anyone had a similar experience?

    yes the can and very often do. please ask your vet to a prescritption for Revolution becuase it is less dangerous. frontline and advantage both have a pretty high incidence of issues. also i dont know what you feed but that could be the problem cats need wet food never dry, grain free food (they are carnivores and cannot metabolize grains for energy), and their food needs to be based on human grade meat not 4D meat which is what all of the catfood you can buy at the grocery store contains. i think that Wellness or Instinct or Merreck for canned food is great and Aunt Jeni's home made ofr life for raw is wonderful (raw is better than canned but your kitty will be fine on canned.) the important part is that it is not predominantly fish, contains no grain, and does not contain by-products. also your cat could have eaten somehting else toxic besides the frontline. household plants and cleaners are really common problems for cats. please bring your cat to the vet even if the symptoms have subsided. he could still be in trouble. good luck all the best

    Cat Reaction To Frontline

    It could very well be an adverse affect to the Frontline treatment. Have you used it before?

    I would take your cat to see the Vet, just to make sure all is okay. It may not actually be the Frontline thats the problem and it could be something else.

    Different cats can be allergic to different things. You could of also gotten the wrong dosage (goes by weight) or your cat could of licked the area where you applied the frontline and ingested it(not a good thing)

    Maybe if he is still acting like how you described take him to the vet.

    Straight from the vets mouth to here. A double dose will not hurt. It is common for the application site to itch for about 24 hours.

    The most common side effect of an allergic reaction is on the skin.

    yes.you may have overdosed him.you need to be VERYcareful with this as it could kill him.some cats have a lower tolerance level than others.

    are you sure you bought the right one? they go by weight and if you bought one that was too much for his weight he was in an over dose state.
