I agree 100% with everyone.. Any vet that keeps an animal for 2 weeks and can't figure out whats going on, isn't much of a vet. One thing that can give cats that kind of problem is worms or parasites. Even the best fecal float can miss the eggs and such. Kitty might have coccidea also, which can start up from the stress of being placed in a new home. The treatment for either coccidea or worms, is inexpensive and easy... I'm sure that "Everyone" on Pet Of The Day is praying for you and your new baby... keep doing what your're doing..
