Hi everyone. I write this with a heavy heart and tears. I'm putting my beautiful Mufasa down today. He has been getting progressively aggressive over the last few months, and this morning, he unprovocably attacked my mother's dog, who he usually loves. The poor dog needs stiches it multiple locations. He tore her up pretty badly. I don't know what's gotten into him. He's been to the vet a few times, but they can't find anything wrong with him. I'm so worried that one day, he'll attack my son, or kill the dog or my other cat. I really don't want to end his life, but don't see any other option. This is breaking my heart. I love him so so much.
