Good luck with your new kitten. I also like the name Annie unless it turns out to be a boy. LOL

Just remember to introduce Tito and the new kitten slowly after the new kitten has had a clean bill of health. I'd also recommend that you have the vet deworm the kitten since he/she is a stray and most kittens tend to have roundworms. I'm sure that everything will work out in time. Please keep us updated and we'd also love to see some pictures of the new kitten.
