Oh dear ! Once you make a connection with an animal its difficult not to follow your heart. What if you promised Paysforit never to step into a shelter again. You are too soft-hearted to be hanging out in animal shelters ! See what the vet says.....draw up a contract promising never to visit a shelter again ....sign it ...have the cats put their paw marks on it ...give it to paysforit.....(with a promise to take sole responsability for litter-boxes).....if this does not work.... do you have friends who might want a kitty ?
