I don't have any I had two hamsters, but not at the same time. My first hammy was called Speedy (he was a greyish colour), and I called him Speedy because he was really, really fast (well, duh, right?) ^ ^;
My second hammy I initially called Hamagotchi *coughs sheepishly*, but then changed "her" name to Fluffagotchi when her hair grew to ridiculous proportions. I say "her" because there was an amusing story surrounding her gender ^ ^; I have no idea what breeds they were ^ ^, but Fluff (for short) lived to be about four years old ^ ^;
Hamsters are actually lactose intolerant. I would sometimes give my teddy bear hamster frozen yogurt and i can't give it to her anymore because i found out they aren't suppose to have that kind of stuff.
My vet said once in a while, just a few drops, won't hurt, unless the animals are allergic with milk or not healthy. It's like us eating burgers & chips. Junk food for a treat is fine as long as the amount is considerable...
Okay! And when I gave my hamster frozen yogurt it was only once in a great while, and it would only be a very little amount. My vet (who isn't all that, and I don't really like them) said to not even give my hamster anything at all that was dairy except for those yogurt drops made me hamsters but only give it to her in moderation.
