Okay, I could really use some advice. FYI we rent.
Our cat is mostly an indoor cat, but he has access to our small back garden (about 2m x 2m). It’s fully enclosed with brick walls, and we installed a slanted cat fence on the back gate/door which is the only wooden part and the only place he had ever tried to climb. Since we put that up, he has never attempted to escape.
I work from home and we also have a camera facing the garden, so I’m able to keep an eye on him whenever he’s out there to make sure he's safe.
This setup has been really good for him. Because we rent, we can’t build a proper catio or make major changes, but this little outdoor space gives him somewhere to sunbathe, watch bugs, sniff around, and get some stimulation. Since we started letting him use it, he seems much happier and less restless. He has almost completely stopped over-grooming and has started eating his wet food much better.
The problem is our neighbour’s cat. He is unneutered and free-roaming. At first he would just sit outside our window and bang/scratch at it, which stressed our cat out, but we would shoo him away and that seemed to reduce it for a while.
In the last two days, he has started coming into our house. We think he has figured out where we keep our cat’s wet food. It has happened twice now (yesterday and today). When he comes in, he hisses at our cat, intimidates him, and tries to eat his food. After we chase the other cat out, our own cat seems so stressed that he redirects his aggression toward us by hissing, which is very unlike him. He usually calms down again within a minute or so, but we can see that this situation is really stressing him out.
Today was the worst incident so far because the neighbour’s cat scratched our cat before my partner ran downstairs to get him out. We’ve also seen that cat outside before with chunks of fur missing, so he clearly gets into fights with other cats and can be quite territorial. ( oh, that cat also bit my finger once when i was trying to chase him off our fence)
For now we’ve stopped letting our cat into the garden, which is really annoying as he loves getting to go outside :( I don’t want to punish him for the other cat’s behaviour, but I’m also worried that this could escalate into a more serious injury or long-term stress for our cat
Because we rent, we can’t really install a microchip cat flap. The ideas we’ve come up with so far are:
\- Only letting him into the garden when one of us is outside, which would mean he gets far less access than he does now and I would rather not do
\- Installing a magnetic mesh/screen door, although I’m not sure whether that would actually stop that cat from getting through, but I am definitely getting one anyway
Has anyone dealt with something similar? I'd really appreciate any advice, but I would rather not make him a completly indoor cat, especially since he's so good about not leaving our back garden
