Neighbouring cats - is my cat okay with them?
Recently, whenever I open my back door, two of the neighbour's cats come in the house. We never let them any further into the house than the front room, and usually my cat's in the front room with us. My cat is 13 this year, and she's always been the only cat in the house. She used to be really anti social with the other cats in the area, but she doesn't seem all that bothered with these two cats coming in.
In fact, right now Dinah [my cat] is sitting on top of the bookcase next to the back door, and Dora [one of the neighbour's cats] is lying in the doorway. I'm not sure whether Dinah really is okay with these cats wandering in, or if she's maybe too scared of them to chase them out. She's quite a bit older than them, so maybe she just isn't up to the running.
She seems quite relaxed, just lying down with her eyes half closed. She's fully aware the other cat is in here, and she watches her when she wanders about, but she doesn't seem angry with her.
I know Dinah likes to protect me, so she usually sits up a bit when the other cats come close to me.
Also, we have two gerbils in the front room, so we don't want the other cats getting near them.
I want to be able to leave my door open, especially on hot days, but I don't want to do it if it's making my cat uneasy; it is afterall her house.
If it mean anything, my cat and both the neighbour's cats are female. Dinah's been spayed, but I'm not sure about the neighbours, because one of her cats had kittens not too long ago.
