My Cat Cosmo is a DLH, and is about 8 years young. Typically he has always been a large cat, despite measuring out 1/4c food 2x/day. However, I have 2 cats, and Bailey is a DSH and thinner. So Im guessing cosmo must be getting more than Bailey. Cosmo has had urinary blockage twice and was on CD/Urinary dry food. But we switched a couple months ago to N&D Quinoa Urinary food. I am now noticing Cosmo is drinking more water than usual and seems to be getting fatter! He is an indoor cat, pretty sedentary unless he is playing with our dog. Other than that, nothing else out of the ordinary. Cosmo is a very affectionate boy and I'm hoping nothing serious is going on.
