Because I'm absolutely crazy...

[PWCorgi]

He hasn't seen any other cats while he has been here!

I would definitely suggest fostering before bringing one home, especially since he probably hasn't seen another cat since you found him. Even just with new people in the apartment he can be quite timid (until you hand them the da bird, of course ).

Plus once you get him back I don't think you're going to want another cat for quite some time. He's turned into a bit of a monster
I think Megan was quite appalled last night when we were eating and even with 4 people sitting at the table who were placing him back on the floor, he still managed to spend most of dinner on the table and even got some ice cream I have never seen an animal with such a high level of determination!
