one of our cats, smudge a really affectionate cat, had 6 kittens in may, she was 10 months old, a perfect protective mother to all the kittens. we have kept 2 toms, which have been castrated. she was great, her personality changed totally, she only comes home to eat and when she is here she is a spitting demon. we already had a neutered female who was 1 when we got smudge, they got on very well.
sorry this is a long post, we took her to vets and she has had blood tests for thyroid probs etc all came back clear. we are really concerned and wondered if anyone has experienced simular or can shed any light on our problem thanks
