I noticed lately, in Harvey's litter box that some of his poos have a bit of white stuff on them or a sort of clear substance of some sort. His poos are a bit small and in the last week I saw cecals a couple of times, but not in last 2 days luckily. Appetite is fine, increase in hay ingestion, but less water intake. I noticed him laying down chewing at one point today. Could be in pain, but doesn't look that way. Last Friday he was in ileus (got taken to vet). But seems to have recovered fine, minus the smaller poos (but I mean still a good size), and cecals. Anything to be concerned about? Thank you!
