No, but we use this one from Amazon and it works well. You place a plastic liner in the drawer and sprinkle the powder on it and it turns the liquid into a gel making it easier to dispose of.

I'm glad you took her to the vet, that was going to be my first question. My childhood cat lost control of his bladder and uncharacteristically peed in my bed the day before he suddenly died of an infection.
I don't have any great tips. I'm sorry this is happening to you. My only thing would be to try pee pads around the house, a different style of litter box (some cats will only use a "roofed" litter box), maybe catnip/spray near the box or positive reinforcement when your cat uses the litter box... I don't doubt you have already tried that. My only other suggestion is to stop allowing your cat on the bed. By repetitively putting her down and saying "no". That's what I do when I find my cat on the stove counter or any very high furniture because it's dangerous. Times you're not there to guard your bed, something like a shower curtain draped over could help. Since you're newly moved into a new home, you have a little advantage of a new atmosphere for the cat to learn new habits. Easier said than done, I know. Sorry for the crappy advice. I'd struggle to keep my cat off the bed, and he's a very good listener. I'm truly sorry you.
Is your cat fairly old? I assume the vet did a good check of her paws... if her paws are in pain, that could be why she prefers a fabric texture
I found this dog potty with a grassy texture. Would that be something you'd consider?
