Thanks to this my three year old sister is potty trained. I've tried stickers, gold stickers, panty time, 2 hours on the toilet, and some really good gold coins, but the odds that she potty goes and does it are still 2/5. I bought her cat pants so she can even wear underwear and I thought I could use these. I tell her that the kitten needs to eat gold coins, so in order for her to run and feed the kitten, she needs to earn them. . Now she washes her dishes, throws out the trash, uses the potty and lets me comb her hair, all thanks to this little cat! Batteries inserted and small batteries removed. The main reason I can't give it to her to play with. The edges are sharp, be careful.
