thank you for all your replies!
unfortunately, I am severely allergic to cats but thanks for the suggestion. It was a good idea.
i did have 2 playdates a week for him over the summer but since then, there aren't as many people out walking about (i live in the city).
I'm not going to rehome him b/c i love him so much! He has millions of toys to play with so I know that's not the problem.
I'm just going to try to get him a playmate as soon as possible.
I know that would make him really happy.
Thanks for making me feel like I am being a good mother
