Hi there, Sadly we lost our four and a half month old kitten on Monday. I am absolutely distraught that his life was cut so short, so soon. We have had him since he was 9 weeks old, he went for all the regular injections and was flea'd and wormed before we got him. We got some flea and worm treatment to give him at home but I was so worried about putting it on his neck that I'd put off doing it (we vaccummed his scratching post and the room we kept him in regularly). We kept him in a special pen when we went out for long periods (and if we couldn't directly supervise him he had his own room for safety) and he was allowed to roam freely when we were supervising him. Recently he had periods of lethargy but we chalked that down to kittens getting tired and he still had spirts of energy and would play. His appetite was great and we saw nothing in his poo that would indicate worms though we intended to worm him very shortly (I was a little scared because he used to bite me a lot and I didn't want him to get the treatment in his mouth). He used to pick anything up in his mouth so we were careful to watch him as much as possible. He did play in his litter tray a lot which we tried to stop him doing. I brushed him regularly and noticed that he might have fleas as there was some dirt on his bed, but I'd never seen him scratch. Our other cat goes outside and was flea'd when we got the kitten but they only had brief contact in the day and didn't share beds. Our recent visit to the vet we were advised that he was a normal weight but that his tummy was a bit round so he could have worms. On Monday my partner phoned me to tell me he had died. He had found him in his bed (my partner had been tidying his another room so had put him in his special room). He had been sick and vomited a worm (which we think was a tapeworm, which the wormer we had didn't cover) and was unrousable. I wasn't there so I couldn't see what had happened. Later that evening we found sick along a the ceiling of our bedroom and the curtain, where he may have played whilst my partner cleaned a his room out. My heart is absolutely broken as I don't know what caused this and I feel like it's all my fault. Can anyone shed any light on what it could be? I miss him so much and I can't help feeling like I've caused this. Thank you so much in anticipation of your help.
