I've fostered hundreds of cats for local rescues in the past 8 years. In the past few years, I've gotten to the point where I only take seniors, hospice cats, or special needs kitties. I have a long-term foster who is diabetic and hyperthyroid. Up until yesterday, he's had roommates to share the foster room with. His last roommate was also diabetic, so it was pretty easy to manage their diet since they ate the same food. But sadly, his roommate passed away yesterday and I don't think it's fair to keep him in a room by himself. I have nine other cats and he gets along fine with them, but I free-feed them a mix of urinary health and sensitive stomach food. How do you guys manage a single diabetic cat in a household that has other cats that are non-diabetic? It's not feasible for me to feed each cat individually.
