Thanks everyone, for the kind words and support. It's always hard to lose one of the little guys (or girls). They bring us so much joy and we do our best to give them a good life.
I've been crying on and off since he started to go downhill last night. There was a point last evening when it looked like he was starting to improve. When he was stretched out sleeping with his leg out and his head on my leg, so I was hoping that was a good sign. Soon after though, was when he started to steadily decline. It's so heartbreaking. It's so hard to watch them struggle at the end, for every breath and then the seizures start and there's nothing you can do but be there to comfort them.
I'm staying in bed today.
