Kitten advice needed

We also like "World's Best" and "SWheat Scoop" biodegradable/flushable litter.

It costs a little more, but lasts a long time and isn't as messy.
You just remove the waste and keep using the rest.

We flush the poop, but due to being on a septic tank, we just throw the pee clumps out the side door and the rain eventually takes care of it.
