Hi, I am really worried. My pig, Eddie, was okay a few days ago but now he doesn't seem to be able to use his back legs as well as he used to. I noticed him hopping rather than running and he won't come out when the food bowls are clinked together, (this is the feeding bell). He still eats when it's near him and I thought it might be an impacted rectum (he was a bit messy down below when I checked him today) but, even after cleaning his nether region, he is still unable to use his back legs. There is some movement but it's only for a really short distance. He didn't even run in to his hut when I went to pick him up (this is something he will always do at least once before he lets me grab him). Please can someone tell me what might be wrong with him. I am going to take him to the vet tomorrow but it would be really reassuring to know that it's nothing serious! (P.S. He hasn't fallen and he gets on really well with his fellow cage mates so I don't think he's been attacked by one of them).
