I'm sorry to hear that.Thanks for your reply. Today is the 4th day after Io was applied Revolution. Since yesterday she has lost appetite and become much less active. I understand this should be the side effects of Revolution. Did you see the same effects on your cat? This is the second day that Io refused to eat her favorite canned food. I am getting a little worried...
Besides, looks she still scratches herself. There are some new scars on her ears.
Our cat didn't have any adverse reactions to the Revolution as far as we can tell.
Has your vet done any tests lately to see if there's something else going on?
