how to scent one food item with another

[ThemandUs]

I've never had to scent one item with another before. my snakes have always been good eaters or leaving them alone in a small box with the item has gotten them feeding. but mky carpet is really resisting rats . he will only take mice and its getting annoying. so howm do i scent a rat with a mouse? do i just rub it on it ? het them up together. whats the technique?

also is it true that rats give a snake more weight ?


thanks
