I have a 2 year old male tabby and a 6 year old female tuxedo cat. Both of them are slightly overweight so I started feeding them this dry cat food for a little over a year. 4 month ago my male cat developed urinary track blockage (crystal) so we have to keep him on canned food diet. We couldn't be sure the exact cause of the blockage (food, stress, genetic...) My female cat would not eat canned food so we let her keep eating Pro Plan's Weight Management dry cat food.

Now my female cat got urinary track  blockage as well!  I am kicking myself have been keeping her on this dry food.

Do not feed your cat this food. Urinary track blockage is very costly to treat. Once they get it, it could be a life long battle. Be carful!

My female cat has been on diff brand of cat food (Wysong)since I took her off ProPlan's Weight Management Formula. I noticed her skin flakes improved! It also made a huge difference in the amount of pee she produces. This is a good thing and will help to keep any future blockage away.
