What fun pictures - that second one is great! You should sooo nominate Niko for Pet of the Day!
That reminds me of the time when we were living in a "no pets" apartment, but had a little rescued Siberian Dwarf Hamster. The landlord was having people come do maintenance on spring day, so we took Vadim, cage and all over to my friend's house. As we carried him out to the car, I saw the crabapple tree was blossoming, and thought - "Hm, wonder if he's like some lowers to nibble?" I broke of a twig with a couple blossoms and set it in his tank, and before I could even get the lid settled back down and cage ion the car, he had emerged from his corner, and faster than you can imagine, buried the whole flowers for safekeeping, just a bit of twig was sticking out!
