How would I "euathnize a rat fuzzy/pup

[marmie]

I have a burmese who I fed a live fuzzy/pup rat. I want to see if it eats frozen so I can buy bulk. If I buy the bag and it does not then it would be a waste. So I want to buy a live one to freeze and feed it as a F/T to test him out.

It's only one. Would smacking it's head against a hard object do it?

Please don't smack it! See if your local pet store or reptile store has some frozen. Even Petco sells frozen in small quantities.
