Hi, we have a 7 month old kitten who was let outside for the first time about a week ago. So far he has only ventured out into the back garden and seems very wary/nervous. Twice now a local cat has chased him inside and today cornered him and attacked him. Any ideas of anything we can do? I've never had a cat before so have no idea. I'm assuming this cat is trying to assert his authority/claim his territory? Our kitten only goes out during the day. Thanks in advance.
