his name is Gaudi

Meet Gaudi, i bought him today at an animal shop in centre ville. I've wrote in my previous post how another soul would add life to our surrounding, so here it is, a pet of my own. The first since i arrived here in France.
Why i bought a hamster? well, i've experienced with cats, turtles, fishes even birds(a family of pigeon who made their nest on my window) and a cactus(who've died eventually, its amazing how they manage to survive in the hardest part of the world like Sahara but died in my old room, please don't judge me base on that because it was a long time ago...), so now i want to get my hands on something new.
Gaudi is a 'Roboroski Hamster' or its scientific name is Phodopus Roborovski.
i found the name roboroski doesnt fit with such cute creature, it fits more to a robot who can ski.
The owner and the net says it's very active and im now agreeing with them.
Why i choose him? first, i thought of buying another type, but on my 2nd trip to the shop (the same day) i found this little guy(i think its a male, never did ask and i havnt investigate yet) in a big glass cage with no other hamster. Sitting there, all by himself.
Long story short, he's unique and he wont be missing his friends if i took him.
you can see the photo of his old cage, there's no more hamster since the only occupant has been taken.
Below is his new house and some photoshot of him.
i've read in the net that i should use a bigger cage and the one without bars. but i've already bought this one and after a few observation, i dont think Gaudi would get himself out through the bars or even get stuck in between.
