FYI my daughter was told by a vet to use meat tenderizer for poo eating problem. After she gave it to the cat, bloody urine, incontinence 2 days later. 2 more days the 3 yr old was in hospital. After being out for 2 days he began the same problems. I found out and came here. Started him on ACV, and cranberry. I really can't imagine what meat tenderizer does to the insides of cats... Tenderizes it at best. 1 day, so far, into ACV treatment. Tail's is much better.
