I have three cats. One of them absolutely hates the other two and throughout the summer she's pretty much spent all her time outdoors, sleeping on top of our shed and only coming in to eat, hiss at the other cats and then leave again. If I shut the doors and windows to try to keep her in she just paces and cries so we've been leaving the window open and letting her come and go as she pleases.
Just to mention she has been checked by the vet and nothing appears to be wrong.
Now the weather is getting colder I'd like to get some sort of shelter for her for if she does continue to spend all her time outside. Any recommendations for something I can make or buy that will keep her cosy? She will always have the opportunity to come inside but she is so resistant at the moment, I'm not sure if it'll change!
