Oh man aren't Newfoundland's HUGE dogs??? I would be so worried that Ari wouldn't know how to hand that sort of situation..... Dogs for a cat that hasn't had a whole lot of exposure to dogs can be a BIG adjustment. But such a big intimadating dog of that size would be my biggest concern but you are a smart cookie I am almost postive you know what best for your kitty....That has to be a very hard decision to make when you also have to look out for his special needs you'll do what best... Thanks for a idea on the foster kittens I think I will be much better off charging for vet needs...Thanks!
