Hi Tigger,
Cats grow very fast. That's why I always regretted not taking enough pictures of Nanook when he was much younger.
The crystal beads, brand Litter Star, is quite good actually, albeit a little expensive. It's odourless, and you dun have to change the litter. They were saying you could use the same litter for a month? When the cat urinates, instead of clumps, the beads turn yellow, at the same time, absorbing the unpleasant smell and moisture. You just have to remove the poo. I tried it out on Nanook once, but he was more interested in the beads. He spilled them everywhere, so I'm stuck to using granulated ones.
Yes, they want to stop owners from keeping cats in flats. Sigh, I am glad I dun stay in a flat anymore. But anyways, if you keep the cats indoors always, they won't create trouble, and since you have already spayed or neutered them, they won't, I quote them, caterwaul. Have you girls emailed Cody already? Perhaps I should rope in my friends' help.
