Hey I know how it is! Chris usually spot cleans of the snakes before I'm even home, and I go and play with the rats when I get in!
FrankyKeno also recommended this, get a bucket to keep in the fridge with the left over, and at the end of the week, split it out to the rats. They LOVE it! LOL, my rats are totally spoiled. They get the crumbs from cereal boxes, left overs from dinner, stuff like that.
There is a short list of what not to give them, but generally they can eat what we eat.
