Thank you everyone for your replies. I expected that most of you would say go get him! I suppose I posted to see if anyone would say "no, you irresponsible idiot, you should never get another cat."--I've had that thought repeatedly. Guilt is a nasty, sneaky emotion.

Boots will likely be arriving tomorrow or Friday. I am off work tomorrow--the last day of my worst holiday ever! I will post pics when he arrives.

Thank you again for the replies here and for the support over the past few days. It has been a blessing.
