My cat was put on Mirtazapine today because he's not eating. He will take a couple of bites of food then stop eating. I gave him his first 7 mg dose at about 3:00 and stil nothing. I've tried everything, Fancy Feast, baby food, tuna, chicken, warm milk. He won't touch anything!! We've been back and forth to the vet and all tests are normal. I don't know what else I can do for him, should I try a second dose??
