My English Spot/Dwarf rabbit is almost 2 years old, I've had him since he was 5-6 months old. Earlier this year, in May, he had the same symptoms: shaking/feels like spasms from his head to his scruff area. I don't know if it's when I pet him, but whenever I do, he shakes. Like what happened in May, he was perfectly fine before everything happened, he was actually more active than usual, so I gave him a few treats. Three hours later, my mother said that he was lying in the litter box, he stayed in there for more than an hour. When I came down to eat dinner, he switched to the stairs(his favourite spot). I went to see what was wrong, and I felt that he was shaking from head to scruff and that his stomach was VERY soft. Usually his stomach would be bouncy, a bit hard, and note that he sat in the litter box, and we can't tell if he did poop or not. Anyways, how should we help him? He seems to respond to me, so I don't think it's a seizure. When it happened in May, he was perfectly fine the next day. It is a little cold at our place, it's around 4 degrees celsius, but the last time it happened was in SPRING. I don't want to risk not helping him anymore, my parents don't want to take him to the vet because they're assuming that he'll be fine, and that the cost is too expensive. But just because the first time he was okay, doesn't mean the second would be. How should I help him? I need help, thanks.
