Well..I feel absolutely awful. I've been working really hard with Twinkle and things had been going so well. She was accepting treats from my hand inside the cage, she was learning to hop into a jug, get a treat and then be lifted up and put back for a treat. I thought she was ready to explore a little on the bed. Spoiler, she absolutely wasn't. At all. She was up and about just now so I figured why not try, since she was happily accepting treats.
The second she stepped out of the jug and onto my bed, she bolted blindly in any direction she could. I managed to catch her and got her onto my lap in the hopes of reaching for the jug, nope, off she went like a bar of soap almost getting off the bed, in the end I abandoned the jug and managed to scoop her up and pop her back into her cage.
I am absolutely covered in urine, hopefully all hers

she frightened the life out of me, but clearly not as much as I did her. And what's worse is even in all her terror, not once did she so much as squeak or even attempt to bite me, I had resigned myself to get bitten pretty badly at that point because my first thought was "what if she gets off the bed and the cat finds her before I do!?" So keeping her in my hands was the biggest priority. But she didn't even try!! She's such a sweet, gentle little hamster and I frightened the living daylights out of her.
