Oh, poor fella! I can understand why he is stressed, I'm sure
Corkscrew is also picking up on your stress level as well. I have heard that many times cats know excatly how you feel, and he's just as concerned about his mommy being stressed too!
Not to mentioned what he's gone through before he came to you.
Soon you all will be settled, and Corkscrew will realize all is fine!
Good luck to you in your new place!
Please give Corkscrew some belly rubs and head sctritchies from me!
Sammy and Romeo send him some headbumpies too!!
