I now most vets around here are sooo willing to take in an animal in need....they can either do arrangements for payments, etc. If this little guy is sick, I am afraid to say it, but maybe finding him a good home would be a wise choice for him too...and a vet can help w/ that as well. I know you love the little guy already, but that is an option too.
You and Madison will be in our thoughts and prayers!!!
