Hello,This evening my rat (Rupert, 7 month old boy) suddenly darted madly around the house for no apparent reason. He had been quietly sitting on my arm while I was sitting on the floor, when he suddenly jumped off and ran all around the house, ending up in one of his favourite spots in a couch. I eventually managed to pull him out, but he was very lethargic and almost 'floppy'. He's still young and normally wouldn't sit with me for very long, but he spent the next hour and a half lying in my jumper. He also wasn't interested in his favourite treats. I've since put him to bed and given him some water, and he's slowly eaten a bit of food that he would normally eat with gusto.Does anyone have any idea what might have happened? I figure if he was startled and then just needed to calm down he would be acting normal by now (3 hours later). I would greatly appreciate any advice!
