I once had a 20 year (yes, 20 year) old rabbit named Nugget. You can guess why the name...Anyway, when he turned 10, we had to soften his food for him. We would mix his food nuggets with warm water. Also, we would feed him soft food like yogurts, etc. He actually got so old that he didn't have any teeth. We also often times fed him liquid, vitamin-fortified food through a dropper. Other than not having any teeth, Nugget was the same old bunny we loved.
Yeah, it's sad when I think of how short life is for our furbabies. The vet has a longevity chart for dogs and cats in the waiting room. One of the key factors for expanding a pet's life is to give that baby lots of attention and love. From all of the pet stories that I've read on this forum, I think that all the Cruise Addict fur and feather babies will live long, long lives.
