I'm also a bit suspicious of 'special' yoga. I'm not talking about the different types such as hatha, kundalini, ashtanga etc, each of which has its own valuable path; no, I mean things like 'cat yoga' as featured in the Sun recently. According to the article by Jenny Francis, Lady Dinah's Cat Emporium in East London hosts cat yoga classes twice a week. That's not yoga for cats, it's yoga with cats, wandering around purring and wotnot. Sounds awful to me, but I've not tried it, so I shouldn't judge. Certainly Jenny liked it.
Instructor Bess Shipside is quoted: 'Lots of yoga names and words are taken from the animal kingdom.' Indeed they are. What's next? Meditation in the reptile house? Postures in the milking parlour?
