I've not really got onto shaping with this game yet, so far I'm just encouraging them (esp Zorro who's always been a bit afraid of experimenting) to try out different things. Bella's got it down to a tee, I was working with this cat scratching post which has 3 branches off it (like a mini tree) and a dangly toy. Bella targetted, very methodically:
middle of post
top of branch 1
bottom of branch 1
top of branch 2
bottom of branch 2
top of branch 3
bottom of branch 3
pulled on the dangly toy
she then thought "aha, I can do the same but paw them all"
She's too clever, good job I'm not paying her in money or I'd be into a serious overdraft...
I did discover though that she has really learned the difference between spin (clockwise circle) and twirl (anticlockwise), and she can now do spin/twirl/spin/twirl all on a row before getting a treat, she was going like a little whirling dervish
