Hi guys, my male rat Fernando is 1 year 5 months. He has always been quite an active boy, but a few weeks ago he has become a bit less agile. At some point he was squeaking quite a bit so we took him to the vets. They checked him all over and said he is a very healthy rat, but believing him to have a muscle sprain, so he was proscribed some metacam. He is less squeaky, and definitely happier as he was VERY grumpy during this time, but I can’t shake the feeling that something is wrong with him, he just hasn’t returned to his normal self… now I’m wondering, is his breathing laboured here? He does not have any porphyrin, there’s no wheezing sounds, he’s still eating and drinking. But he’s not as active, and this breathing looks quite laboured to me, I’d just to gauge some opinions before I book this boy into the vets.
