PPA, Phenylpropanolamine
We use this for “leakers” which are dogs with relaxed (too relaxed) urethral muscles allowing them to leak urine especially when sleeping. Dogs get up from a urine/wet spot.
Used to control that with hormone replacement and it worked. And worked to cause other problems. Now we use THIS medicine and it works, too.
And yes, (little did I know) very occasionally a cat can have this. With the same presentation as dog “leakers” —> Getting up from urine puddles.
