i saw many on the internet, but then i went to petsmart and they had one that i had been looking at so i got it there. my friend thinks i am crazy too, but i told her you don't have a yorkie so you don't know how caught up one can get with them. they have little spirits and they are kinda like little people (not literally before anyone goes nutso on me). so we like to take them with up when we go down town to walk by the water and such. we have two kids with dance, soccer, football, basketball, with all of that they would be alone too much. this allows us to take them safely out with us.
anyway we love it
