Okay so long story short it’s been a hot week in the uk, I live in a flat so I keep windows open and curtains shut. On Monday I decided to put two frozen water bottles in the cage to keep them cool while I’m at work. When I got home, he was begging to get out his cage, he does like coming out his cage but his eyes were wide and breathing was fast. I noticed he wasn’t eating his food even tho he usually eats his food too fast! So I let him out. I put him back in and usually 30 mins is enough for him but again he was begging to come out and still not eating his food. Like he was spooked? So I gave him food out of his cage and he ate it out of his cage? Then after he ate I put him back in, but he wouldn’t settle. He wouldn’t go to one side of his cage. I changed his bed around and he still was freaked. 3 days later his only just started eating his food in his cage. He usually has bath mats in his cage but I put sawdust in there last night and he seems a little bit more comfortable. He usually drinks lots of water but he hasn’t touched it so I’ve been giving him water foods like cucumber and trying to give him the water by hand. He still seems very timid which is unlike him as his usually my confident one. (His in a cage alone for the last 5 months due to fighting with the other which lead to bites) since coming home tonight I’ve noticed his voice is a bit raspy and he can’t seem to scream for food but has ate some. He seems to keep weeing on himself which his doesnt usually do and Hasn't done as many poops. And also when his cleaning himself his hair is sticking up a bit. What do you think it is and what do you think I should do? Sorry for it being so long
