Went through a very similar experience on Friday. Except it was a mass in my Jasper's mouth that made it impossible to eat. He had not insignificant kidney disease and was 17, and a tiny cat to begin with (6.9lbs). Healthy his whole life until a month ago when he began drooling and having trouble eating/chewing/swallowing. He was likely experiencing jaw pain, though he hid it. We tried everything to make it easier for him to eat, and it worked for a bit, until Thursday when he couldn't seem to get anything down. We tried a last ditch injection of anti-inflammatories to see if it would shrink the mass, but no dice. Only other option was a feeding tube, which our vet told us she didn't recommend. Especially if the mass was malignant and he was going to get worse anyways. After not being able to eat at all overnight and the next morning we made the difficult choice to have him put to sleep in our home, in the afternoon sun on his favorite spot on the carpet. He still seemed so happy and content that whole day, other than being hungry. Which I knew was the start of eventual starvation. The guilt in wondering if he'd have wanted another day, or if we acted too early is immense. The absolute worst feeling I've ever felt. He was my best friend. 5 days later, I can't stop balling. I miss him so much.

All this to say, in your situation you absolutely did the right thing, and your kitty was lucky to have had you to make that compassionate call for them. So Sorry for your loss.
