My 10 year old Birman is behaving very strangely. Loud miaowing when she is outside , we have a cat flap but she won't come in very often . During winter she was inside all time but has been outdoors day and night . She'll come in for food but is not eating very much.
I came home from work today , it was pouring with rain and she was outside trying to keep dry under the bushes. I tried to get her I'm but she ran off again miaowing loudly. She has never been a particularly affectionate cat and has not bothered much with us . do I need to take her to the vet?
