Yes I know what you mean, much easier with an English site isn't it.
If you're after treats off rodipet these are really good for encouraging natural foraging behaviours. Keeps them occupied and usually go down really well with dwarfs. I have to limit them a bit with my robo as she can't seem to restrain herself haha.

The flower mixes are also nice, generally use some of those with some herbs and birch leaves (rodipet) and it provides a good and natural foraging environment.
