Lol Im up too One cat, my siamese is always up at this time of the day so she gets banned from the bedroom when she wakes up as she is a loon tearing about the place and my other cat has just come into heat and is pacing and non stop shouting
It sounds like youve got the same thing but like you I have never had a cat with kits b4 so I dont know how soon they come into heat I hope you get it sorted soon and get some sleep I should think the more experienced cat owners have it susssed and are all fast asleep!!!!
