So I've been worried about my big baby Bobo being all by his lonesome, he came for a cage with three others but has been alone since beginning on january and my gf is too worried he will just hurt the babies so... I was thinking she's at work during the evenings while I'm home ... Should I work on introducing all three of them? Or is Bobo at 18 months to old to introduce the 4 month olds? I've had their cages next to each other for two weeks now. Also a side question none of them are neutered and I wanted to get Bobo done but my vet said not to do it unless Bobo becomes to aggressive or I want to give him a female companion is he misinformed? Or is Bobo too old? I just see so many shackers with their ratties spayed or neutered. If its a good idea for the neuter but also if you guys think the intro is a good idea I will post vids of how it goes. I'm going to start with neutral intros in the bathtub first if it all looks good after a week I will move to the play area intros (my floor) ... Good or bad idea?
