My British Blue was having some bladder spasms and was diagnosed with FLUTD. I feed Acana (grassyland) for dry and a host of wet foods as well. After talking with an Acana rep this morning, she told me to cut down on how much Acana I am feeding and put him on an Urinary Tract Wet food. Thought about Purena Pro Plan Focus Urinary Tract Health canned food. Is this a good plan? Or what do you guys recommend? Thanks
