I have a male cat that is about one and a half and he recently lost his sister that was from the same litter. So they were really close together. He has Feline leukemia but he is in perfect health right now, he has constant vet visits so I know he is fine. Well before he lost his sister we would cry a little bit in the early morning and stop. But since his sister passed away he will cry for hours, usually when it starts to get bright out. So I don't get up until 8 that's about 3 hours of him crying. I tried to let him in the bedroom but that doesn't help either. I am not sure what to do now.
