My cat had kittens in February about mid month (both mom and dad are ours and 100% healthy) i picked one out during week 1, a male... The litter was 2 of each gender. The kitten was 100% fine for the first 2 weeks.. Eating from mom etc.. Though he did section himself off from the others rather often (he would go lay with dad instead or by himself completely) we thought it was just a personality thing till later in week two when one night we woke up and he was in the middle of the room (had escape his enclosure with the mom and others) and was cold.. He stopped growing after that, stopped eating from mom (we started bottle feeding him) and seemed to have a cold often. When he slept he sometimes shook .. Barley could walk .. Not even half the size of the other kittens, head was always down.. He was doing AMAZING thurs-friday and then saturday during bottle feeding he passed- out of no where. Note: we DID talk to a vet- but they wouldn't treat kittens that young. The best we could do was what we did. I would really like some certainly as to why he died, some closure. Thank you.
