PrettyLitter is by far the best cat litter I have ever used. At first, I loved it because my cat adapted to it immediately, it is light, and it doesn't smell even though I have a small apartment.
For the piece of mind alone it is worth it! My cat is 15 years old, and last summer PrettyLitter turned blue (too alkaline). I am a nurse and I couldn't really see any behavioral indications that there was a problem. I was a bit skeptical, so I waited about two weeks to see if it would clear on its own. I figured that the statistical odds are that in 14 years of life he's likely had another infection and it resolved on its own. I do not recommend waiting, and I will never gamble like that by waiting again! Some infections just need antibiotics, and his body may not clear infections as easily at his age.
Anyways, I brought him to the vet and the vet felt crystals in his bladder. Being an awesome vet that he is, the combination of feeling the crystals and the alkalinity indication from the PrettyLitter was enough to prescribe the antibiotic. We were able to avoid the additional charges and tests related to the normal best diagnostic practices. I'm not working as a nurse right now, so that was a financial blessing!
I honestly think that saved my cat's life. I've had to put a cat down before after being unsuccessful in saving him. My son will be devastated when it is time for our current cat to go to heaven. I'm just glad it isn't his time yet!
Thank you PrettyLitter for keeping our family whole.
Bottom Line: Yes, I would recommend this to a friend
