My boyfriend and I have noticed that Ossian hasn't wheeled much in the past few nights. Either he hasn't wheeled at all or not enough that is noticeable during the night while we sleep or in the morning by the poopiness of the wheel. Also, last night, I was awoken by a very strange noise coming from his cage. It was some sort of squeal/vocalization. I was pretty out of it and can't remember exactly what it sounded like now, but I jumped right out of bed and checked on him. He was inside his igloo snuggled in his fleece blankies and was quite huffy when I picked him up (not abnormal, especially in the middle of the night) and I have no idea what made him make the noise. I got him out this morning and set him on the floor to watch him walk around. He walks completely normally, his belly is warm, his nails don't appear long enough that they should impede wheeling. He is still eating and drinking normally and his cage is kept at a constant range of 76-77F.
Any ideas about the strange squeal and his lack of wheeling?
For now, I plan to raise the temperature of his cage a degree or two in case he finds his wheeling area a bit chilly for his liking. Also on Thursday I plan to clip his nails after buying new clippers since mine did not seem sharp enough to do a very good job last time.
Any other suggestions?
