Sorry for the long post, but this is my first post and I feel it is best to give the details up front - apologies if it is TMI! One of my two little kittens (supposedly from the same litter but we have our suspicions) has always been on the small side compared to the other. He has been through the mill recently with multiple vet trips. First it was cat acne, for which he was given a pink liquid we have to dilute and wash the chin with. Then it was a bout of diarrhoea. Scribbles has had soft stools before, particularly if food is changed in any way (even between the standard Felix and Felix as good as it looks). I worried he might be stressed, competing with our other kitten, but often Scribbles is the one who starts the fights and pushed the larger cat away from the food - so he seems to win all the battles. Then horror struck... after a particularly wet toileting I checked he didn't need help to clean himself and found he had a small anal prolapse. Freaked out, checked the web and it said it can happen when a kitten strains too much but normally goes back in on its own... it did, and I calmed down, but then it popped out again as he walked up the ramp to his feed station - cue a worried trip to the vet. He was given a paste and pills to have twice a day and we had to feed just boiled chicken in 5/6 small portions a day... This seemed to clear it up and he happily went back to pouches. By this time Scribbles was finally big enough to get neutered - his brother Digby having been neutered maybe a month or so earlier! I had hoped this would reduce any competitive stress, but it seems after the surgery the diarrhoea has started again. First, whilst still at the vet... I put this down to them feeding him a different food to what he is used to, but then all day the following day there was loose stools and lots of them. And he had another anal prolapse. So I decided enough was enough, it could not be nice or comfortable for him and he wasn't doing it in the litter tray (probably associating it with painful eliminations. A few checks later, including the dreaded finger check of the anal sacks and we are no clearer on the problem, we know the prolapse is because he is straining to toilet, but what is causing the diarrhoea we do not know... possibly just a sensitive kitten. This time the meds are a pouch of powder - Pro-Kolin Enterogenic. For cats under 5kg it is supposed to be half a pouch a day (bearing in mind my kitten is just under 2kg fasting weight the vet said half a pouch would be ok.) Since giving him the powder he has only urinated in the litter tray, no stools, solid, soft or otherwise... I am now worried that he might be a little constipated and this might lead to bigger problems with straining - but I am at a loss as to what to do, withhold food, continue feeding but stop meds, deliberately try something which would usually cause looser stools, or just wait and see what comes out of the poor little mite... Any help, advise or tales of similar woes would be very much appreciated... I am a very panicky kitten mum, but what else can I be, when he has been so poorly since the start and can't tell me what is wrong! P.S. even with the loose stools, cat acne and now lack of stools he has been playful, greedy and attentive, he loves nothing more than to eat, play with the wrong end of any stick and dangly thing toy, and to cuddle up in the tightest space he can find!
