My name is Cocoa and tank!

We have two cats that we are looking to get adopted. They are mother and son so need to stay together. The mother, Cocoa is a smaller long-haired pure white cat. She is about 10 years old. And her son Tank, who is nine years old and is a big boy... about 20 pounds with shorter hair. He is all white, big and snuggly. Our daughters have left for college. we have two small puppies and the puppies and cats do not get along. So we are looking to find a home for the cats- either permanently or long-term temporary until the girls graduate from college and settle down.
Both are indoor / outdoor cats.
