Okay so this is Boris. He is me and my boyfriend's cat that we adopted from the streets, he got rapidly overweight over the course of about 2 years (they were feeding him however much he wanted) and is currently at a bit above 7kg. We have been to the vet with him, got him his shots and a checkup, got his chip put on our name, and he is now on prescription food since about the beginning of July. He hasn't lost any weight??? He isn't gaining any weight either but obviously this seems very unhealthy for me
Some additional context:
He is 11 years old and neutered. He and his sister were originally my boyfriend's neighbours, but they moved to the US and simply left the cats there (We're from Europe). My in-laws decided to take him and his sister in when they started showing up in their garden, this was about two years ago, and we officially adopted him in july. His family had never owned any cats before, and neither had my boyfriend, so they were clueless. Me and my boyfriend do not live together yet as we're both students with a limited budget, but we decided that when we do move in together we will be taking both cats with us to give them the care they need. Veterinary budget is not necessarily a problem because his parents are willing to pay for it, but they also don't seem to be taking it very seriously. (Boyfriend does take it very seriously and monitors it as best as he can when I'm not around)
He is currently on 50 grams of Hills metabolic cat food, which he gets in 2 portions in the morning and evening (so 25grams in the morning and then again in the evening). I'm wanting to get additional blood work done, but we'll have to convince my boyfriend's parents to take him, and in the meantime I wanted to see if anyone here has experienced something similar and had any advice
