Pongo has seemed absolutely fine until about an hour & a half ago when I got home. I immediately went to feed him & Gizmo. They are usually very excited & wait anxiously to get their food. Gizmo was still excited but Pongo was laying in the corner of his cage & didn’t move at all. After feeding Gizmo I sat in front of Pongo’s cage & tried to get his attention. He was laying all smushed down in his “sleepy bunny” way, as if he had been napping. Normally, this would not concern me, but after shaking the bag, pouring food in his bowl & making it perfectly clear that there was food to be eaten he still did not move. I tried hand feeding him a piece but he just sat up a little & repositioned himself.
Also, when I got home, I noticed that he had peed outside of his cage. He hasnt done this in years(this is what initially concerned me). I picked him up, flipped him over & did a quick look to make sure there was no gunk in his eyes, nose, no dirty feet. Everything LOOKS fine. After I put him down he hopped into his litterbox, where he is still laying down. I tried to interest him in food again but nothing. I looked at his water bottle & he has been drinking, but not quite as much as I would like. He ate hay this morning &, like I said, seemed perfectly fine.
One more thing: When I was just over by his cage trying to offer him food again I noticed he was breathing very, very quickly & his nose was moving faster than usual. I don’t think any of this has to do with heat because it has been very cool in my room, so my main concern is if this could be some kind of urinary thing? I’m quite concerned 
Thanks for any help!
