My Maudey has had another uti brought on by stress, the stand in postman knocked on the front door and scared her silly and last night she started classic signs of wide eyed hopping in and out of litter tray and spots of blood in litter, anyhoo she saw an emergency vet today and seems much better already touch wood, but my regular vet suggested these Zylkene before for her and I did hope it was a one off last time but alas it seems not to be, so has anyone experience of these and how they effected the cat, oh and I already have a feliway and she's on csytaid already.
