We have a cat visiting our garden too... for a few months now.. and it always then disappears back over the far wall to where it lives/comes from. And when it did more recently, I heard a man then shouting really horribly, 'Get out, get out!' And a woman said, "Do you keep it outside?". I'm just concerned if this man is the cat's owner, he may have thought at one point: don't want it - if I leave it outside it'll find food and fend for itself (how ignorant). When I rang a cat rescue they agreed that it sounded like it had been dumped and happens far too often, and people too lazy to get it rehomed, so just leave it to roam the streets.
The cat is not that old, and is coming around at all hours of the day and night looking for food. It quickly sneaks in when the door's open and has tonight even jumped in through the upstairs bedroom window. It's a beautiful looking black moggie, but I can't keep having it coming in the house. I have my doors and windows open in the summer. My own can come and go as he pleases, but even he's now anxious if the other cat is around, especially when he's eating. He does chase it out of the garden. We have fed it occasionally because if it has been 'dumped' we can't see it go hungry and it mieows so pitifully.
I keep meaning to put a paper collar on but if the man is the type I think he is, he probably won't even bother responding and judging by the language I heard, would probably tell me to eff off and mind my own business. Cat rescue have said take the cat to see if he's been microchipped, though they think probably not. And even if it has been dumped, there's a waiting list to actually take a cat to be rehomed!
This is becoming a burden now. It's affecting my cat, I'm fed up of closing my doors, when it comes in it wanders around the house (when we realise that it's inside), and I've no idea what it's bringing in. As much as I love cats, I don't want another as it's not fair on my own cat. This cat has obviously not had any training, it jumps on top of everything, goes everywhere... none of my cats were ever like that. We'll be going away in September for a week and it'll have to fend for itself. That might break the cycle. (I've also heard other neighbours complaining about it.)
