sick cat

[goosy610]

Our cat is six years old, he is an indoor/outdoor cat and has been immunized against everything offered in MN. He has been healthy and happy for six years.
Last week Tues. night we gave him his usual dose of frontline plus for cats.. never a reaction before. The next morning he was throwing up and drooling alot. he seemed better in the pm. Thurs. he had no appetite and seemed listless but we called the vet who advised watching him to determine progress.
Fri. morning he was the same but all of a sudden he started wandering aimlessly around, his eyes were completely dilated and he seemed blind. We took him to the vet.

The vet did blood work which all came out ok except for high potassium. They treated for dehydration and sent home.
Our cat now has his eyesight back but has no appetite, is extremely lethargic, and has little coordination in his back legs. It has been three days. He has urinated since being home. Even breathing.

Does this sound like an allergic reaction to the frontline as it happened so sudden or could this possibly be kidney disease? The vet checked for that and there was no sign.

Any possible treatment or advice? Our vet's next recomendation was to take xrays which made no sense to us...

CORRECTION:  The frontline company must keep a LOG of adverse effects


Sorry about the spelling error!

P.S.  this may not be from the frontline but from exposure to another toxin if your cat had gone outside after you placed the frontline on.

Thanks so much for getting back to us!

I would call the emergency number on the frontline box and discuss this devestating episode with the veterinarian on staff.  The frontline company must keep a lot of adverse effects, and must record this episode.  There may have been a problem with that particular dye lot of frontline.  I would also bathe your cat multiple times with baby shampoo to see if you can remove any residue of the frontline, though it may be a bit late.  I would take your cat to a veterinary neurologist just in case.  Frontline may even pay for it.  

Good Luck!
