Hello All,
I am still new at this... so be gentle...
I saw on here before that A&H kitty litter was free after MIR but I also found that Feline Pine and Dr. Elsey's Precious Cat Litter are offering MIR for their products.
I know that the A&H and Feline Pine ones are reposts but I thought that some people would want them in one thread so that it would be easier to find. So here are the links to the the rebate forms:

Dr. Elsey's Precious Cat Litter - any size, no expiration date listed.-- I found this on the Petsmart website so hopefully, they have it in store.

Feline Pine - Good on 9 or 14 lb size only (new size), expires 3/31/2012-- Any grocery/ pet store

For Feline Pine, there is also a $1.50 off coupon so this could be a money maker! This coupon can be found at http://www.felinepine.com/

Arm & Hammer Ultra Last - 20 lb size only (new size), expires 3/30/2012-- The 20 lb one is available at Walmart.

Also, for A&H, there is a $1.00 off coupon that can be found here: http://www.armandhammer.com/Resou...enter.aspx

As mentioned elsewhere, Target has the 28 lb box for $10.89 with a sticker on it for a $8.00 MIR and if you use the $1.00 coupon in the link above, the total price (plus tax) for the box will be $1.89. ***Thanks to mprice12 for pointing out that you can use both the Walmart and Target rebates as they are two different rebates.***

***Here are two more FREE after MIR litters thanks to josh1234***
"Worlds Best Cat Litter"-- Any pet/ grocery store

There is a $3.00 off coupon for WBCL if you go to their Facebook page.... yipppeeee! https://www.facebook.com/worldsbe...1836112061. ***This find is thanks to ohmichea***

And Feline Fresh (This one is more like BOGO as you have to buy a bag to get a coupon for a free bag)-- I have searched (in NJ, at least) and I think that this sells only at certain pet stores so you should check yours!

Even if you don't have a cat, please take some time out of your day to purchase these for your local animal shelter. They need all the supplies they can get!
