Thank you for your help
i knew younger was better but you can never quite know the age of one from a pet shop.
My story is quite long but I will shorten it.
I started off with two females Grace and Gizmo from a pet shop, they were my first robos. They never really got on and i separated them. I then found another female in the adoption center (Pippin) and brought her home to introduce to Grace. but I reintroduced grace and Gizmo since they both seemed quite sad even though Gizmo was the bully.
Anyway, unfortunatly little gracey died and i miss her so much because she was the tamest and i spent two weeks looking after her with antibotics and she knew to stay still and would sit in my hand.
Iv had Pippin and Gizmo is opposite sides of a split tank, changed sawdust and toys over and had them in a playpen with a mesh between them and after 4 weeks they still hated each other. I think i did everything right :-S
Gizmo is too obsessed with food to share it or even her space and prefers being left alone which is fine with me
i just watch her.
i had to separate them completely because in the split cage they both because territorial and really nippy with me. they are better now in split cages.
I defiantly have the space for more hamsters if they have to live apart. I will just move some of my stuff.
I will stay on the lookout for breeders near me. I live in sussex.
thank you again
