Very cute! What type of shavings u use? Can't really tell.
btw something with owning dwarfs is their complicated diet. Dwarfs are very prone to diabetes and cannot have any corn, peas, carrots, fruits, or any store bought treats. All of these foods contain sugars. Natural and un-natural sugars. Dwarfs can get Type-1 diabetes which is passed from the parents or type-2 diabetes from eating to many sweet foods. So it is very important to stick to the diet. Thsi means you must pick out any of these foods from the food mix. And you can't get any treats from the pet shop for them either. they always have some sort of salt or sugar in them.
Robo's are very fast and usually nervice. It can take a while to tame but you should never ever give up.
