Accidently put Dog Flea Repellent on Cat

Wednesday August 6, 2003
This recent forum post highlights the importance of following labels when using chemicals and medications. From the forum - kckroq asks: "We accidently put the dog flea repellent (like Advantage) on our cat. We bathed him about 4 hours after application and when we realized the terrible mistake we made. He seemed better, so we went to bed for the night. When we woke up, the cat looked like he was in shock, shaking, eyes glossed over. He is at the vet now getting fluids but they are not sure what to expect. Has anyone else experienced this?" Here's hoping that they made it to their veterinarian in time and the cat will make it!

We did the same thing. Put the flea medicine on the 10 pound cat meant for the 80 pound dog. Our cat almost passed away. The vet’s office did the bathing, and that didn’t help. We took him to a vet hospital which had overnight service, and they hooked him to IV fluids, and watched him all night. He survived our stupid mistake, but it could have easily gone the other way. I now keep both cat and dog meds separate. I wear my reading glasses and check and recheck before applying any medications. It was frightening. I hope your cat makes it throught this. All the best,

I have heard horror stories like this.. I am so paranoid when I put the cat’s on then the dog’s I check and recheck.. they should really be labled better..or differently in some way.

My poor little 4 month old kitten Ollie is in the vet hospital right now because I put my 120 lb. dog’s Advantage on him rather than the cat advantage. He has a fever and twitching. The ER doc is keeping him overnight. They are giving him baths, IV fluids and he has a 70/30 chance of pulling through. I’m devastated.

Advantage for dogs has an ingredient called Pyrethrine (sp?) which is toxic to cats.

Wish us luck!

cat and dog advantage are the same.. it is the amounts that cause the problem.. I had a lot of cats and would do all the cats with a single large dog dose divided up.. I used a syringe for accurate measurement ..r
