Heres the background
We have 2 cats, a boy, 6, George, neutered, and girl, Minnie, 5, spayed.
Someone is peeing in the house, once a day only. It's not a small amount, it's a full bladder load. Normally on the carpet, but preferences on bags, any clothing left around and lately, toys.
I think it is Minnie that is doing it, but not 100% sure. We have never caught them doing it, even though its been going on now for almost 3 years. I've tried everything I can think of, litter trays, different litter, trays in different places, feliway, locking down rooms, cat only child free areas...... But still, every day I have to go through the house sniffing trying to find today's place.
We are now at the point were we can't live with this for much longer, and certainly not put up with it till they are of old age, and we are starting to seriously consider rehoming 1 or both of them.
It first started when Sasha came home, but only once or twice in a 6 month period, then when Oliver came home it became more regular building up to daily a few months before we moved from Torbay.
Sometime after Sasha was born, George got crystals in his urine, and is now on royal cannine urinary biscuits, which means Minnie is too. These have fixed George crystal problem, but due to this, I blamed him for a long time for the indoor peeing. I'm wondering maybe though if there is a link here with Minnie?
When we moved to mt Roskill, I was able to segregate the cats into two parts of the house, but only for a couple of days, and the mess was in Minnie's half, not George's, but I was unable to run the experiment for longer to really find out 100%.
So I'm wondering a few things. Is it the food? Is it the kids? Is it that Minnie would prefer to be an only cat? (It did take her as a kitten to accept the year older George, and he just wanted to play with her) or could something be physically wrong with her?
Any thoughts?
