My wife and I have had our boy for 6 weeks,he's 6 months old, he has gotten comfortable pretty quickly.he is friendly toward other animals and has become friends with our neighbors 80 lb Labrador. We have just adopted a 4 month old f3c. After the vet check, since they are both young and relatively new to this place, can I consider introducing them to each other earlier than two weeks, or will I encounter any problems
