So I got two rats in March both boys... A month later I found out one was a girl and the other was a hermaphorodite... Well in June my Hermy rat died from a freak wheel accident resulting in a broken neck.,. I was unable to get another rat until September, I got two 6 week old rats! Well last month one of them got. Respitory infection and It was progressing very fast so I made a vet appointment but they said they couldn't get her in for 3 days and she passed away that day before her appointment ... Well I have been trying to introduce my remaining two for the past few months, and idk if it is working... Sam (my oldest rat) has been alone since June, and she is very skepticle of Meg (new rat). Meg is about 4 months old so she is pretty little compared to 11 month old Sam... Well I put them in the bathtub a few times to meet I set out toys and hidey places and treats and they were good! Well Sam ignored Meg, but Meg kept climbing underneath Sam and just sitting there... Sam didn't like it much. They sniffed each other's lady bits, and groomed each other a bit then Sam flipped out and rolled Meg over and Meg squeaked and Sam ripped out Meg's hair! Idk is this normal? So far so good? No blood no injury... But I want them to live together I HATE Meg's cage it takes forever to clean its a horrible cage... Sam went into a depression before I got Meg.. She's been perkier since even though they aren't together Sam is never aggressive toward me or the sibling (idk how to refer to it cause it's a he/she)... It seems like dominance? I put them in each other's cages for about an hour and came back and switched them back again and then after a few minutes put them back in the tub...again same situation Meg wants to be under Sam at all times idk why, and Sam wants to go about her own thing then they sniff each other and they are fine for 20 minutes or so before Sam like... Attacks?
