Sorry no-one replied sooner. I hope the hog’s poos have returned to normal now, but in case not, the following is an extract from one of Stef’s posts from 2019. ” …….. hogs do have a fast gut transit time and it’s not unheard of for them to occasionally pass a green poo. However if it’s regular then the hog is ill
Also bright green shiny/slimy if most likely to be a poorly hog”
Although you may not have fed him anything different, he may have found some other food himself.
If the hog still has green poos, it would be a good idea to contact your local carer/rehabilitator and take their advice – that is, if you haven’t already.
Good luck. I hope the hog is ok now.
