I have recently got a cat, I have had him about 2 months now I think. He has started to go outside and seems to like it, he comes back (one exception to this) when I shout so don't think he goes far.
He has begun to have fights/disagreements with another local cat which has been here much longer than he has. When they meet up they growl at each other but I've only actually seen them fight once.
The other cat is much larger than my cat and one day I heard the growling/miaowing and when I went out to look the big cat was at the top of the close stairs preventing my boy from coming back up. He has also prevented him coming back into the garden once.
I wondered what the best thing to do in this situation is, I realise that the older cat would have established my garden etc as his territory and now my cat is "taking over" but I guess they just need to sort that out. When the big cat has been preventing my cat getting in I have gone out and chased big cat away and brought my cat inside.
Is that correct/an ok thing to do or should I be leaving them to sort it out themselves. Is there anything I could/should be doing instead.
Thank you for any help, this is my first cat so not sure
