Thanks Claire, your always so supportive and great!
And Thanks Anya, your help and your self-knowledge has been a huge help!
Also, thank you Lisa, I read the links and they've helped, also the other things you've said has helped to. xxx
Anyways, I've made up my mind that I'm not neutering Husky. I don't think it will help him that much and I also think that I wont be as satisfied with what I get for the money I spend and over here it's expensive, probably over £100, though, if I did think it was gunna help than I would.
I'm going to leave Husky to settle in the spare cage and get used to being on his own and I'm also holding of any play dates until Husky has finally settled into a home of his own. Once he has, I will try another Introduction and if that doesn't work out than I'm going to buy him a cage of his own and leave him on his own from there on.
If Husky is already happy on his own without the others, and no play dates, and no intro - I may just go straight ahead and let him stay on his own, with occational supervised play dates.
I have thought about this, and yes, I do think I have enough time on my hands to keep a lone rat happy and give him what he needs.
Thanks everyoe for your help, I've appriciated it!
