Wow! He's gorgeous. The same thing happened with Cirrus. A lady adopted him and his brother as little kittens and kept them until they were 6 months old. She said she returned them due to allergies. She never held them or loved them either. This is the reason why Cirrus is such a stressed out and scared cat.

I'm sure that Pumpkin will get adopted quickly and hopefully this time it will be in a loving and real forever home.
