I think this man really loves his cats and they like to perform, but when they were on tour here a few years back, Finnish animal welfare societies raised two issues:
1. He doesn't believe in spaying/neutering, the cats have kittens all the time, he gives the kittens away to fans. It's quite a strain on the females, not to speak of all too many street cats in Russia already.
2. The cats don't have enough space, at least according our animal protection laws, which demand at least 3 square meters per cat (thats' the legal minumum, 10 square meters per first cat, 4 per every cat after that is reccomended). The cats live in very crowded circumstances, travelling in his trailer as I recall.
For these reasons our animal welfare societys suggested boycotting the cat circus. I don't know what to think really. On the other hand I kind of think it's not right to make animals public entertainment, on the other hand, from what I've seen on TV, the cat's really like to perform. I decided against going to see the show, but wouldn't judge anyone who decides otherwise.
