I give Pudden fortiflora for her chronic constipation, but I am getting tired of paying the high price for it. I would like to find a replacement as it really does help keep her regular. I was looking at the Now brand on amazon and was wondering if it is suitable? I believe that most people give 1/2 a capsule twice a day? Can anyone give recommendations on what they use or if the Now brand at that dose would be good? I also wanted to make sure it is safe for a diabetic cat. Thank you!
