Hi I recently lost my female Guinea pig BooBoo she was 4 1/2, so i got a new baby guinea pig big to keep Yogi (BooBoos cage mate) happy and i managed to slowly introduce them and they became very close, but yogi is quite old and sick so is constantly having trips to the vet and lots of medication so we thought we should bring them inside as its meant to be a cold winter, we bought a 100cm indoor cage. As yogi is quite sick we thought it would be best to get another guinea pig to add in so that if Yogi passed away Peaches wouldn't be lonely. We called up the pet shop and luckily they still had peaches sister so we bought her. I've tried to introduce them but it didn't go well, Peaches kept launching at her with her teeth ready, but Yogi was not too bad since then Yogi has accepted Pomme more or less but Peaches has not. We added one extra floor in the cage to provide extra room for the three of them. Pomme was in there for the first night last night but everytime Peaches comes near her she cries (squeaks) with submission but Peaches still goes and pulls out a bit of her fur making Pomme Cry more. I read online that maybe Peaches is just trying to assert her dominance so i therefore assumed it would stop soon enough as no one was getting seriously injured it would settle down soon. But Pomme is very timid and hardly comes out of her snuggle so i put hay, water and dry food upstairs so she could get it without seeing Peaches but she still won't really come out of her snuggle what should i do? ( sorry for the long speech) they're all females xx
