I’ve had my guinea pig for about two months with out any problem. She’s about a month and a half old. So I decided to get a new one so they can bond. I reached out to a rescue and they had one female named lea she’s at least half a year old ( 100g bigger) but that said she was antsy. I wanted to give it a shot. The two were placed on neutral territory and they seem to be getting along well. They rescue worker was impressed on lea’s behavior because she had problem finding a whole once before. So we decided we will take her then 5 minutes after we left the rescue they started to fight. And lea started to chatter her teeth. So we separated the two until we got home. Lea keeps chatter her teeth and they got into a fight again. She also chases my Guinea pig into a corner and I’d separate the two until they go their separate ways. ( I truly don’t think these two will get along at all) Any help Or suggestions? Or should I just return the New Guinea pig?
