Hello, can someone tell me what this is? Is it possible to treat at home ? I try not to take him to the vet unless absolutely necessary cuz he is so prone to stress and seizures. If he needs medication can someone please tell me what he needs so I can make sure my vet gets him the right thing since they aren't very experienced with rats. ( I got to another more experienced vet 2 hours away for bigger issues but I get medication from this one right next to my house ) Also don't mind his nail, he got injured during a seizure. Thank you in advanced!
