I had 3 female cats (mother and 2 kittens), the kittens are 4yrs now and I’ve never split them up
One of them was hit by a car over a week ago and passed away
Now the other sibling won’t come back into the house, she refuses the cat flap and so I leave a window open all day so that she’ll run in for food when noone is around but for safety purposes close it at night
I have a cat flap but she refuses to use it, I feel like this is how she’s grieving but I hate her being outside all night in the cold and rain
I can’t catch her as she runs off if anyone gets near and was skittish to begin with
Has anyone experienced similar? I’m at a loss do I just let her start sleeping outside?
