I started investigating house plants as the Guinea Pig Magazine wanted an article on what piggies could eat. It would be a very short article as I didn't find a single plant they could eat unless it was a food plant grown on a windowsill.
They are all not piggy food, but some are worse than others - eg a pine in the house at xmas can be munched a bit but any bulbs plants are really poisonous.
If your piggy hasn't eaten much then they will hopefully be fine. You would see a change fairly quickly and as you posted 6 hours ago the piggy should be showing any affects. Just to be certain, please pick them up and put their side to your ear, you should hear digestion gurgling noises and as long as they are there then all should be well.
And if there are any piggy slaves who haven't held a piggy to their ear then please do this. You will then know what good breathing and good digestion sounds like.
