Feeling totally overwhelmed and upset re my cats

[username24]

As the title says I'm not dealing very well with one of my cats..

Bought as siblings and have always got on fine.

I had to cancel there insurance a few weeks ago..you know what's coming..a poorly cat. To cut a long story short the vets aren't 100% what it is but there has been a lot of blood and wee. I've been back and forth which has been very hard due to my job and keeping an eye/quarantining the unwell one.

Jump to a couple of days ago and he's become a totally different cat. Aggressive, doesn't use his litter tray, is brutally attracting his brother, literally kicks his food everywhere like he would deal with the litter..

I'm exhausted and he's v hard work. Has anyone had this?

My boy was quite cruel when he was in pain (in his case, stomach troubles) - he'd roughly attack his beloved friend for no reason and generally be a nuisance. He's transformed back into a complete cutie now it's all resolved. I'm guessing that the cat has even less of a clue about what's going on medically than you do right now, and he probably feels rubbish. Have you told the vet that his behaviour has changed recently too?

The litter tray thing is likely to be because he's started associating it with pain, too, and they find such things humiliating. I set up a second one with different litter for mine under similar circumstances and it worked well as a stupid trick.

Briette yy we had this as well? We had kitty poogate incident 2009 which completely traumatised her and she took matters into her own hands (paws) and refused to use a litter tray ever again.

Basically she was new, nervous, went to poo and accidentally splattered poo over the living room door by upturning her litter tray too ferociously by ferocious little scrabbling paws. We were all traumatised, she was horrified, I had to go out and buy marigolds and dettol instantly, there was kitty poo sliding down the wall, and she refused to ever use a litter tray ever again.

Kitty poo gate l.

Thanks for the replies, yes I hadn't stupidly thought about the association. I've used every litter going though and they don't like/others so how do I tackle that side of it?
Briette sorry I shouldn't laugh but oh dear!!
