Wow - lots of food for thought! I will let you know what I decide
So I will let you know a few things - I do have a bin cage, I use them as play pens with different substrates in and different things for exploration, eg grass, soil, sand etc. I am trying to build my collection of those up.
When I was breeding and showing I kept all of my hamsters in bin cages and I did like that you could customize them. I ended up with a variety of different cages, depending on the hamster - tanks for the escape artists, even a rabbit hutch for one very active individual. I liked that because you could tailor the cage to the hamster.
My current hamster doesn't require additional taming - this is a photo of her that I took from our bath tub sessions. She was hand reared and we believe that perhaps she has a neurological disorder, nothing big or anything, it just makes her a little quirky.
She doesn't mind hands and contact or anything like that, she just doesn't like to be picked up. If you hold your hands still she will crawl up them and all over you, she just doesn't like it if your hands move.
Which is fine, because usually I put a small storage tub in the cage and she climbs right in and then I transport her like that.
I just find it more difficult in the cage she is in. She doesn't like overhead movement and I feel that if I were to enter her cage from the side she would be much more amenable to coming out. Plus I like the idea of her having more ventilation and I would find it easier to clean.
At the moment she has to be in the tank because we have cats but we are moving house and I am going to have a craft/hamster room and I want her to sit next to my desk so that we can interact whilst I am working too. If she were in a barred cage that would be much easier.
I should have made that a little clearer. She gets a loooottt of time out of her cage, which is great, but if she had a more accessible cage it would make it easier for me.
When I was breeding and showing, the hamster heaven was the be all and end all. It is interesting to come back into it and see how much perceptions have changed, I feel like Britain has had a very European influence in the last few years that has been really great.
So I love the Alexander small pet cage. Gotta do some more research between that and the little friends cage - the others are just too expensive on Amazon.
