I need to ask a favor...

This is Teddy.  Some of you might remember him.  When we got him, he was so skinny, and his hair was so thin that he shook like a leaf with the cold even in the middle of the summer.  So the first thing we did was buy him a tee shirt and feed him.  He's in much better shape now.  His hair has come in much thicker, and he has some weight on him, so he isn't cold all of the time, though he still has some more weight left to gain.  The problem is, his tee shirt has become his security blanket.  Most of the time, he's okay without it, but when he gets anxious or stressed, he asks for his tee shirt, and we put it on him.  He has some anxiety issues, and when he gets too stressed, he gets sick to his stomach and can't eat.  We're worried about what will happen when his tee shirt wears out.

This is his tee shirt:



The Petsmart website sells it here, but they only have it available in x-small, and we need a small.  It's a Petsmart exclusive product, so what I'm asking is if you can, please look through your local Petsmart for this Captain America shirt in small.  I am willing to pay for the shirt and the shipping.  We would like to have at least two extras.

This would be a really big help.  Thank you.
