When my Neutered ~2-1/2 y.o. male indoor/outdoor rescue cat quit eating late March I got nervous and took him to the Vet. He was about 1 y.o. when I rescued him and he's been on Purina Pro Plan True Nature and Fancy Feast cat meat exclusively for last 1 yr plus. he enjoys a little grilled chicken and pork chops when I eat it. The Vet. did a full physical exam and blood work and told me he could find no problem. The Vet. gave me Mizertapine to give him every 3 days and he immediately started eating again, although not as good as usual. I went through several weeks of giving pills and then he seemed to do a little better with no pills. I found some different Fancy Feast he would eat plus I let him free range some kibble. He will beg for food and he might eat a few bites of cat meat only to walk away, then a few minutes later he may come back and eat a few bites of kibble. Mid May he seemed to quit eating again so I got another round of pills (4- 1/4 pills or 12 days worth). He did okay on the pills. 6/1 I took him in for Vaccinations. His weight was about normal at 10.4 lbs. 6/3 he wasn't eating well and turned down several varieties of canned meat but ate a few bites of kibble. 6/4 still not eating much, his last pill was about 4 days ago. In my exasperation and emotional upset I decided to take him to the Vet. again. I let Vet. run more tests, full blood work, urine etc. and an Xray. He found nothing abnormal but did make a comment that one kidney was a little larger but dismissed it as a problem. He gave me several more pills and told me he would refer me to a specialist if I wanted or he could do an ultrasound. He had lost .6# between the 2 Vet. visits (3 days) which I find suspect. I remember at the time I got Vaccinations that I thought it was odd he weighed the same as original Vet visit as he looked thin to me.The day after all the tests and xrays I decided to let the Vet. refer me to a specialist. 2 days later they called and said they would do the referral. I asked where it was and it was 165 miles away at a University Vet. school hospital. I asked if we could find something closer and she said yes. I told her I wanted to wait a week as he seemed to be doing a little better, she said fine. Tomorrow afternoon he is due another pill and I think I am going to try tough love and see if he will eat without the meds. I am thinking now I may just let the Vet. do the ultrasound and if he finds nothing else he can refer me to a specialist nearer than the 165 miles away. I have tried so many varieties of cat meat and kibble I can't list them all. Sometimes when he turns his nose up at something he normally eats I can give him a treat or human baby food and he will start eating, sometimes he turns it all down. He pretty consistently will eat kibble but not enough to gain weight. Since the last Vet. visit I got a scale I could weigh him on and he is back to his normal weight or above slightly. I would appreciate any help/comments. Sorry if I rambled and I am sure there is a lot of details I may have left out. He doesn't act stressed/scared that I can tell.
