Agree completely with last person. One of my male cats died a few weeks ago from a bad urinary blockage. Acute went to critical in one weekend, of course when regular Vet offices are closed and special pet emergency clinics charge a fortune which is disgraceful. Heck, they don't even return phone messages or emails. These animals are not like cars not starting -- flesh & blood the doctors take an oath to care treat. I only once had to try the AVC remedy and it worked on two cats. That was years ago. Now I have a male not peeing and a female barely peeing. They're not pooping much cause they're eating little. I tried three days of ACV & antibiotics. No results. I'm going to try something different again with ACV. It is so stressful for caretakers. I've shared my home with cats for 50 years. Only one death from kidney trouble. Cat was 23 yrs old! Nowadays cats keep getting sick with urinary and GI problems. It's gotta be the food.
