He needs to be fixed, if he gets a female pregnant it is a danger to her. And you are supposed to tape up their ears before they are 6 months old so you need to cut the hair as close to the skin as you can and then tape them each up and tape them together for one week and if they are red and swollen when you take the tape off you need to take him to the vet because he has an ear infection. I dont know if there is another way to get them to stand up, thats the only way I've heard. And welcome to YT!
