My kitten is only 6 months and he has been wanting to go outside for ages. Last week we let him out and he was very happy about it. The first day, when he came back home his tail was very brushed. The second day we let him out, he was out for one hour and then he came sprinting from the bushe's and was manically bashing on our door. I suspect that something is scaring him, maybe because we live near a park and he saw a large dog , I'm not sure. But lots of the other cats in the neighbourhood seem to not have a problem. He is always chattering at the birds, but runs away when we open the door for him to go play. I don't really want him to be an indoor cat already, how do I encourage him to want to go outside again??
