I just bought some equine pine. Whats the best way to transfer my cats from a clay clumping litter to this? I put some into the pan and mixed it in with their litter and one of my cats peeked into the litter box and stared into it like there was an alien inside. I'm afraid she might not use it-maybe I put too much in to start with.I use Equine Pine for litter -- it's for horses but just like Feline Pine, in pellets, which dissolve into sawdust when it gets wet. It costs less than half as much as Feline Pine and I get it at the feed store. $5.99 for 40 lbs.
