Stray cat maintenance and feeding

So I guess its official now that we have a stray cat that we are now feeding. I have complained previously about a cat meowing outside my bedroom window last summer. First the story was that the cat was a neighbor’s cat. Then later I was told that the neighbor’s had moved out leaving their cat behind.
Initially I was quite sympathetic. A poor abandoned cat. Then I remembered a few months ago the gardener had complained on several visit that a cat was using my garden as a toilet. That information I found very irritating. We actually went through options to keep the cat away. In the end I decided to do nothing at all. After all, I dont sleep in the garden.
The garden visits became common and the meowing became constant. Weeks later, my informant turned cat feeder started making comments of letting the cat come inside our place. Needless to say I put them straight. I am an animal lover by nature. But we all have our boundaries. In addition, I am severely allergic to fur.
The thought of having a wild animal stepping in all sorts outside, then coming to sit in my environment licking themself… tufiakwa (God forbid)…. I not only reject, but I bind and return to sender. Lets not even think about the belief of the general Nigerian that cats are witches… if I ever let this cat in my home, that would be the last time my younger sister Ndidi will ever visit me. I guess that’s one sure way of keeping certain people from visiting🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Anyway… the cat stays outâ€
