Sondhi wants to be wherever I am - and Burt wants to be where Sondhi is.
I find, with my greys, that it can take them sometime to warm up to certain toys. After trial and error, I'm pretty good at eliminating things that will just end up as "art." When I get a new toy, I'll throw in some training. I use the toy as a target - one touch, click and treat (I only use the clicker in the initial stages of training). Touch a little longer, beak the toy, chew it, move close to it, etc. All get clicks and treats. In no time, they are investigating it all on their own.
