I never thought of calling a Vet, but that is a great idea as you know the Vet has already checked the cat well.
Everyone surely posted photos of some beautiful cats! I'm envious! Doesn't seem to be a pedigree crowd either...cool.
Please consider adopting a rescue animal. So very many need a furr-ever home and someone to love them! And if we all spay/neuter our pets there won't be an overpopulation to put to death.
