Lily gets daily eyedrops in the morning. Poor girl has cataracts and glaucoma. I'm not exactly sure on her age (she was somewhere around 6-8 years old when I adopted her), but she is around 16. She is also half deaf.
Sable is on a prescription kibble. He loves it, as do a lot of the others.
The others are all doing well health wise. I think Puff has a touch of arthritis so we are keeping and eye on him. He still likes to get on the top level of the cat trees though.
Good luck with your crew. It's a good thing we love them!
