Check the underside of the bottle for the notation "2" inside of a recycle symbol, and the additional note "HDPE". If you see those, then the bottle is the same substance as that used for motor oil jugs.
If the bottle is made of a crystal-clear plastic, then it's probably PVC. Look for a "3" inside the recycle symbol, along with a little "V" below that. It is not advisable to use these for motor oil: they can be brittle and can crack easily.
The thing I'd worry about with an HDPE kitty litter bottle would be the integrity of the lid. A kitty litter jug may not have a lid that will withstand impacts with liquid behind it, or it may have a wide-mouth lid that's prone to cracking. If so, be careful!
