Wondering if anyone is using D-mannose powder or slippery elm bark for cats who are peeing outside the litter box? I'm going to buy both shortly - Aurora has been peeing outside the litter box for a week now - spent over $600 at the vet last week on urine culture, full blood work, x ray and everything came back normal. She's always been very good about using the box. They said her urine was cloudy so I don't understand by taking the sample by needle how it comes back negative on the culture. Something seems to be bothering her - not sure if this is medical or behaviorial since she has been having some issues with my other cat Mulan lately. If you're using the d mannose or slippery elm please let me know how much you give, how often and for how long to keep administering?
Thanks!
Thanks!
