Louie was abandoned in an apartment.  When I coaxed him out from behind a washing machine, we went straight to the vet.  He was dehydrated - we don't know how long, but, never mind, he now has a forever family for the past 7 years.  The big boy has diabetes (controlled with insulin twice a day) and now asthma (seasonal I hope).  He is the doggiest cat I have ever seen.  He is a big old lovie dove that follows me everywhere and has to be close at all times.
