I gave thumper his evening pellets about an hour ago. Ate the lot as usual. Then started changing position rapidly, clearly can't get comfortable, even rolled over. Knew he wasn't behaving normally. Offered two types of pellet, carrot, water, water with added pro-c probiotic (usually loves the taste and will drink the whole bowl ASAP), raspberry leaves, plantain, cucumber. Won't touch anything. Poos have been a normal size, done lots this evening. Did three poops on his shelf as he was trying to get comfortable. Now gone to hide behind the sofa. I know he's not right, what should I do?x
