Eli was probably about 4 months old when I got him, and it was obvious from the get-go he was special needs. His two littermates were also affected, but to much lesser degrees. I think a lot of it has to do with him being older now (he'll be 10 in April). He's taken lots of falls and all his teeth are gone as a result. He has slowed down a lot over the years, but I think it's more to do with his weight. Has Amy gained more weight, or been more sedentary?
