I worked at one of those animal shelters that uses/recommends it!!!
Reasons why you should use it has to do with the health of your cat. Notice how all of a sedden the scoopable litters were reducing the dust in the litter? The dust the cat inhales builds up in the lungs...and is like making your cat a smoker.
It's been a while since I looked at Walmart's prices, but at the time PER POUND it was more expensive at Walmart... $6-$7 per four/five pound bag at Wal-mart... vs. $20 for a 20 lb bag at most pet stores.
At the shelter, I heard a lot of people come back and tell me what they thought of the pine litter...and I heard one of two responses every time:
1. "It's the worst stuff I've ever tried!!! The smell is worse than ever now!!!"
2. "Wow, that's the best stuff I've ever tried!!! It's GREAT!!! There's NO odor!!!"
I never heard anything in the middle...either love it or hate it.
The difference between these two groups is WHAT they were FEEDING the cat. Those that loved it were using premium cat food with less fillers, and (surprise!) real meat. The ones that hated it were feeding thier cats crap, like Meow Mix, Alley Cat, Friskies, etc...
Rule of thumb: If you can buy your pet food at Walmart, your grocery store, or any place that sells mostly 'people stuff'...it's crap. Including IAMS...
I recommend staying away from Eukanuba, too...
I can explain, but it's a bit of a story.
Just ask, and I'll type it up.
If your cat doesn't like the pine litter, you can mix it wil the old gradually until he gets used to it. You can also pre-wett it to make it easier to bury their stuff, until they're used to it.
Remember, you only want to use a little... When it gets wet it puffs. If you use too much it'll puff-Puff-PUFF right over the sides with use. You only want a thin layer on the bottom.
