I'm not feeling too bad today

I am alway's ok during the day as i'm busy but during the evening's it's horrible lol
I went to bed early and watched Grey's Anatomy then went straight to sleep.
Heh thanks for the smiley Tishi, and thanks girl's for being so sweet
Any cat lover's can maybe help me with a cat problem?
One of my cat's is being a complete arse.
He has decided he is liking pooping on my kitchen floor and will not use the litter tray to poop, only to pee.
There are 4 trays in the porch between 3 cat's. They are cleaned every morning. I haven't changed my litter brand. Nothing has changed at all. Just him

He is bright and his normal self, he is just being a complete plonker! He is eating and drinking fine.
He even did it in front of me the other day!! Just sat there and did one in the middle of the kitchen floor!
OH is going mental and said if he doesn't stop doing it he will have to go

I went out today and got another tray, a covered one. I don't know what else to do!
He has only been doing it for the last 2 week's. He is usually a very clean cat as are the other's. I even tried putting him in the small room downstair's on his own for 24 hours with a litter tray, he pee'd in it and pooped on my floor again

Any advice would be brilliant as i don't want him to go.
I also don't want him shitting on my floor anymore
Anyhow on the ttc front

is defo on her way, headache for 2 day's and now backache from hell meh.
Gonna start the vit's again next month but leave out the temping for abit.
I will see what the test result's say and if i'm defo OV then i might start with the temp's again. See how it goes.
I think everything is riding on the test result's at the moment. If mine come back ok (which i have a funny feeling they won't) Then OH has to go for his SA.
