Ok my Cat is a tuxedo cat so she has white paws. I just got her some new litter but there is all these little blue odor rocks in there. When I was playing with her a while ago I noticed the bottom of her white paws are now a bluish green. Is this going to hurt her?

My avatar approves of your having a Tuxedo cat

Hmmm, probably not - but I would check the info on the package and maybe the manufacturers website. However, my thinking is that if this stuff were toxic to cats it would have resulted in lawsuits and been pulled off the market long ago. And I know that crystal stuff has been around for a while.

If you don't have one, you might also try some sort of "grabby" type mat around the litter box. I have one - it's kind of like astro-turf, and it does get some of the stuff off her paws as she steps away. Not all of it, but it helps.

K awesome, My cat almost looks the same as yours, the white up her face is on the other side and she has a black spot on her chin.

I would consider switching to a different brand of litter.

Just switch the litter. We also had a greenish kind of litter when kitty was still around, and she got her feet green. Did not hurt her, was not toxic, but it looked too funny and she was constantly getting weirded out by the colour of her paws apparently.

My cat was all black.

"Tuxedo cat"? :huh: I think that's what our family's first cat was, all black, except white stomach and paws, with a white bowtie shaped pattern under her nose ^_^

The current one is of the standard short-haired grey with black stripes type, whatever that's called

I guess it's not dangerous for cats, see as they lick even their paws. You could switch brand if it really bothers you or use Sodium bicarbonate for odors. Be aware though that it can dry out her skin. My cat doesn't have problems with that, but we don't abuse the use of it, just change the litter often.

My mum has a cat who is black except for gloves and a patch on his chest . He's a nice one, too -- independent and not interested in long hugs, but affectionate in other ways.

Yes cats are evil, and yes it's plotting to either kill you or enslave you.

EDIT: Wait, wrong answer. It's probably a dye of sorts or crystal residue that got on her pads.

My avatar, who is currently hanging out on the desk next to the monitor just made a rather sarcastic snort. (Yes, sometimes I think he does read...) In reality anyone who has a cat is automatically a servant. If the service is adequate, your first comment doesn't apply.

I'd check the contents on the company website, or check with your vet. There are at least two kinds of litter that are made from wheat or corn if a cat has issues with clay/clumping types of litter, so if you want, there are alternatives.

Meh, the only time my cat gives a [censored] is in the litter box

Change litter brands.
I have black cats, they prefer finely shredded newspaper. Or when outside, where we dump the fireplace ash around the ornamentals.
Why they like ash I have no idea.

Because ash is quite soft, perhaps?
