One escape artist! Now returned to his home inside

This is my new birthday boy Grimalkin. He is just happy to be here, constantly, since he came home.

Please, positive thoughts and prayers for my 17 year old kitty Fitzroy? He lost the ability to walk without falling late Friday, and we went to the emergency vet in the very wee hours at least 40 minutes away in the wee hours sat am. Have meds for him, but I really hope it's only a pinched nerve.
