Is he too skinny? :(

[Amara]

Ok so since I last posted I tried a bigger pinkie and my poor little guy seemed completely overwhelmed. For over half an hour he kept trying to eat the poor thing grabbing it by the waist, butt, poking at it with his nose. He tried really hard but just couldn't get it down and ended up looking quite agitated so I took it out and gave him a smaller one which he downed in a minute.
He is due to eat tomorrow so I'll try him on 2 small pinkies instead because just one doesn't leave a bump on him at all.
I've read that you can re-freeze a thawed mouse and feed it at a later time is that true? I get the pinkies for 50 cents a piece so not a big worry but I'm just curious.
