Just switched to Feline Pine.... woke up at 2 am to find my cat ( Melbourne ) my baby on the floor dying... Feline Pine is the only new thing in my house. My baby is dead now. I GOT RID OF FELINE PINE. MY ADVICE IS TO NOT USE IT AND AVOID AT ALL COST. She was healthy and had no signs or symptoms something was wrong.
