Thank you for taking the time to answer this and to offer me some assistance.
Firstly the cat litter trays to cats is correct - so I dont think this is causing the problem. (5 cats)
Secondly Stella has definitely been spraying (its the posture she is standing upright, tail quivering in the air - and a straight shot out of her (trying to say this politely?)
Where as the weeing is more bum down in a squat position - and loads more liquid?
Food bowls and water dishes are scattered around the house, and treats are left out and about so they can "find" them. And there are plenty of hiding places for them - some so good I occasionally think I have lost one!!
I was in the pet store yesterday and have bout a cleaning product with enzymes in which I've been told will help to get rid of the odour that they can smell where they have been spraying / weeing.
I'm going to try and get some Zylkene at lunchtime today (failing that I can order it online and have it early next week.
Its ok to not rate you till after I've tried it - in case I have a few more questions? Is this ok?
I'm reluctant to take Ebony to the vets - as they normally have a huge fight when I get her back home - so I was thinking to try and not have this issue to get teh zylkene into them first (and then take her when they are a bit more "chilled"
I will update soon - and Thank you so much :)
