My cat, Spots, is almost 1yr old and he lost his brother, Coal, about 1 month ago. Ever since he has been meowing a lot and his meows sound sad and distressed, or like he is calling for his brother. We should him the body to let him know that he died so I don't know... Other than that he eats and behaves normally. We did get three new kittens recently and he doesn't really like them, so maybe they are stresting him out? Any ideas?? Thank you!
