I am so confused! basically I have a 2 yr old male and a 6month old female (who is blind, tailess and very timid). I got the female because the pet shop thought she was male. Soo... today I rang the vet asking if she thought I should neuter the male at which she said no because of his age. Then I thought well is it worth neutering any of them incase they don't get on, which today I found out they definatly DONT... my little female is now traumatised and my male pinned her down and bit her hard, luckily I thought to put a harness on him incase any of that happened. She's ok and I managed to check her out n clean her up but I think I will have to keep them seperate my friend is breeding in a few months and I said I wanted 2 bucks off her (if all goes to plan etc) and so I thought I could still get them, neuter them and put them with my female. But does anyone have any advice? I feel really sorry for my old buck but he I just don't know what to with him! Should I try him with some other rats? Or is it just not worth it?! He is fairly old now but I don't want him to die lonely but I dont want him to hurt anymore rats!!! Sorry this is long but any advice would be apreciated.
