PICKY RATS

I need some advice.

My girls are so, so, so picky about what dry food they will eat. I've bought so many different kinds of rat food (block and others) but they simply will not eat anything that isn't a fresh veggie or fruit. What can I possibly do to change this? I don't want them to get sick eating only veggies.

Oh, and they're about 5-6 months I believe.

Give them oxbow adult rat food. You can just put some in the bowl, and leave it for them. Cut the fruits especially, and some of the veggies for a few days. They will eat the rat food. After a few days, you can give them more veggies. But I'd keep most fruits to a minimum. They are sugary, and fattening, and sugar feeds tumors if they have any, or get any. You can even try to make a mush out of their rats blocks. Soak them in cool water, and mash them up. Most rats LOVE this.

Yep, if you cut out all treats and give them a good quality block like Oxbow. Give only a bit of veggies to start.
