I agree with everyone.
I say YES take him in and be his 'Foster Mom' - After you have him for a week, you'll know if it is going to work out or...
If it does, than you get to be his Momma
and if not,
Than you can find him the perfect home for him here on YT.
Now, just think about this little fella...
He is 4 years old and now he going to be torn apart from the only family he knows. He is going to be scared and he is going to need a great family.
I truly think that you would be doing him a huge favor by taking him in and either keeping him or YOU finding him a great family here on YT.
I am really worried about this little fella. I would really hate for this girl to get desperate and just give him away to anyone, and that family could just be horrible
Please let us know what you decide to do???
