This one was refused:

The only litter my cats will all use. Had one with litter-box issues awhile back, and Dr. Elsey’s additive resolved that issue almost immediately. Have only bought this ever since. The only bad thing is Amazon makes my mailman deliver to my house now… and these bags are a bit heavy. Still cheaper than the pet store!

So I quickly cut, pasted, and edited it to this:

And it was accepted… guess it’s not acceptable to say Amazon is torturing my mailman. At least not directly!
