I would say that is the houseplant was 'sampled' last week it shouldn't be causing a problem this week? I am not an expert but I had a pig that ate something wrong in my garden. A plant in a tall pot so they couldn't reach it - fine - but after it died in winter a long stem fell and she ate half before I got to it... maybe because it was dead and had very little taste. She was ill and just laid in her cage on one side that night not eating. I cried buckets and gave her a little sloppy syringe food every few hours in the night - she wasn't keen but she took it - next day she was fine and back to normal. Like the experts said, they can't vomit so if it goes down it has to go through and that plant would have just passed through in a day or so, I'm pretty sure, and not hung around all week. My mum's rabbit ate a whole rubber plant bit by bit (she thought my little sister was vandalising it) and also some flex from a lamp - luckily not plugged in at the time!
If he's trying to eat he's hungry. When mine have developed gut stasis they refused all food - no interest - no appetite. I'm wondering if something is stuck in his throat, poor boy. I personally haven't given apple core but could you accidentally have given the top end with stalk in? If something is blocking the throat you might have to make the food very sloppy and syringe very small amounts (maybe 0.1 to 0.3ml at a time if he can cope) and just hope some can trickle down past any obstruction he might have - if he has one! It is a bit risky to syringe plain water to drink as it is easy to inhale or choke, so sloppy food should hopefully also quench his thirst and keep him peeing. If he can't swallow it might accumulate in his cheeks. Listen carefully as he chews and rest your fingers lightly behind his ears to feel the vibrations... it should be a smooth grinding action and a healthy young pig should chew pretty quick (try comparing with his friend). If he
is hungry,
wants the food and is
chewing well but can't swallow I would go back to the vet, because if he can't get food down and his pooping slows, gut stasis will eventually develop anyway. If he fights the syringe try offering his friend a little - I did this to prove to myself it was tasty enough because the healthy one gobbled it down.
Sometimes they get dental problems but yours are very young for that. Back teeth can meet badly and not chew properly, front teeth can overgrow and stop them chewing with the back ones, and sometimes they can get a sharp point that rubs on the mouth and is sore. But I think if it is any of these things you will hear or see or feel a problem with chewing and anyway it should not really affect eating the sloppy syringe food - they 'chew' this but it is soft enough to just swallow.
I lost a lovely piggy to a swallowing problem and although we don't know what exactly it was (maybe a growth) it didn't happen all of a sudden. It wasn't like she was happy one day and ill the next. She stopped eating herself, but could still be syringe fed for some weeks without 'vomiting' it out of her mouth... increasingly slowly and she had increasing trouble, but this was over weeks, actually over a month. If yours has come on suddenly it sounds quite different.
Good luck, and I hope you have success with the syringe food. You sound very conscientious owners and he sounds quite a character
