I have a cat, one cat, she was a stray.
I occasionally feed Thomas, the local ginger tom with no fixed abode, have been feeding him for 10 years on and off. He sometimes disappears for weeks.
Thomas has now started letting him self in through my bedroom window. He is told to go out and heads for the back door.
The cat from next door, Tiggy, has tried to come into my front bedroom when I am in there (use it as an office/study) so has one of her offspring.
At 1am I was woken by a cat catcalling, another cat, I have only seen this one in the garden a couple of times, must have come through the bedroom window and was yowling at my own cat in the living room.
They are all trying to move in!
Have they sent a memo out that I sleep with a window open?
Thomas is the only one who is fed, and he only gets dried food so it's not like I'm a gourmet cat restaurant.
The cat that woke me was chased out of the garden by my own cat earlier today, but she doesn't seem bothered with cats actually in the house.
BTW I'm in a bungalow so the windows are not high, and it's too hot to sleep with them closed.
