My husband and I took our one year old orange tabby (Bengal mix?) In to get neutered 2 weeks ago to the day. Surgery went great and he came home same day. We also changed to a cheaper food when he came home. In the days following we noticed he has tremmors, and is showing signs of depression. Had lost weight, and doesn't appear to be acting normal. We took him back to the doctor who did the surgery who couldn't be bothered and brought him out to us to say well I don't know take him to another vet. 2 weeks in and we just changed foods back to the regular brand they eat, all the symptoms have stopped, except for the trembling.we took him to another vet who did a vital test and said it isn't a viral infection. So she wants to do a fecal test to rule out worms. It's all just a mess and we are very upset that out baby is sick.
