Over the last two months Sam has begun vomiting his entire meal roughly every 3-5 feedings (fed twice/da.)
His faeces and urine output appear unaffected although he yowls before movements. He was a large cat (@20 lbs but we cut his food back to 1/2 cup serving in the fall of last year when his hips began "clicking" as he walked. (He has been fed dry food: Kat & Kaboodle for the last eight years) He now weighs closer to 10 lbs.
We have given him hairball medicine and switched his treats to Friskies hairball remedy treats. but are still concerned with his weight loss and the fact that he sounds in pain while "pooping" but not the rest of the Day or night... and, of course, the vomiting every third or fifth meal. What do you think could be going on?
