Like mentioned by Amy, the pellets swell and darken a little. This may not be always easy to see in natural light though, but somewhat easier to see in artificial light. This is one of the two issues with the litter, the other being that the litter is dustier than before.

I used this with my foster kittens from 4 weeks on.

I use for bunnies. Don't know if it can be used for rats.

No. Can not scoop out. Dump the whole thing to trash can when wet. They won't stick together when they are wet.

While I know nothing of reptile care, I would imagine that this would be far too scented to use in a reptile enclosure. 

Hi JessSun1017, This has been shared to our vendor. Thanks,

Yes it has no added chemicals to infect your Kitties claws. 99% no tracking. Cant smell anything after days use. Clean out box and replace every 6 to 7 days. Even best cat litter clumping, can make cat smell like poo from using the cat box. No smell on my cat from scratching up litter. Always clean poo out 2 times aday. But I do that regardless of litter I use and it's easy to take out because you dont have to go digging for it it. Love this litter and so does my Kitty!!

Hi Kcricket, The first thing we would advise is regarding the transition of litter. If you are currently using the silica and are looking to switch to the paper pellets you will want to take that slowly. My advice is below. Transitioning Litters Week 1 - Start with 1 inch of the paper pellets under 2 inches of their current silica litter. Do not mix, as the cat will do this when pawing through the litter. Week 2 - 2 inches of the paper pellets under 1 inch of their current silica litter. Week3/4 - Switch entirely to the new paper pellets This will allow their cat to slowly adjust to the new litter. Scooping We would recommend scooping solids daily &; scooping liquids as necessary. Liquid scooping is the preference of the user. Some consumers do not scoop the liquids at all, as the find the odor control is good enough to not need to do that. We have other users who scoop the liquids every day. Change litter once a week complete - no stirring necessary. Thanks,

Hi Kris418, Yes, it can be used. Thanks,

I use it for my 6 bunnies, but the odor control ingredient they add is very strong. It makes my eyes water, so of course I worry about them. I open all the windows and the door while I'm changing the litter and leave them open for a bit. The scent seems to dissipate fairly quickly. I would try to air out your bun's area a bit after you first put it in the box, just in case. Otherwise, it works great for bunnies!
