Keeping Cat Out of Home?

[Karatema]

Not my cat but it keeps wandering in! What can I do to discourage it please? I don’t want to hurt her but she (don’t know for sure) is a cute thing but I’m already sniffing and eyes itching! I never touch her.
In this weather I like my doors open.

Water spray bottle, give her a spray whenever she appears and she'll soon associate your house with it and stop coming.

Thank you. I’ll do that.

It’s probably shitting in your garden as well….have a check.
Cat owners appear to think it’s acceptable to let their cat roam about people property p1ssing and sh1tting wherever it feels like it.
