I had to post about this. The farm/tractor store where I get my wood stove pellets that I use for litter changed ownership and therefore the brand of wood stove pellets they carry changed. I thought the bag looked different?.. but of course didn't put two and two together until my last old bag ran out and I opened up the new bag. Holy grossness! Horrible "wood smell", loose crumbly pellets, it was awful. Of COURSE my two absolutely refused to use them. I had a tiny bit of the old stuff in my storage bin, I mixed to try and transition, but these pellets are AWFUL! So pee explosion everywhere but in their litterbox. :cry2 How could i blame them though. I could not believe how bad the pellets smelled. And then when they did pee on them, they crumbled miserably and almost made a bigger mess. So anyway, I spent the afternoon hunting down my previous brand (Pennington) so phew we are back to litter box using again, but it dawned on me the comments ice seen on here about how people don't like wood stove pellets or they have to air out the bag to get rid of the wood smell....but who knew they aren't all the same!!
