What could cause this.

[Toddlerteaplease]

Cheddar's wee seems really dark. Thought it was the different litter I used but completely back to usual one. I can't see any blood in it and she's not behaving like she did when she had cystitis.
She's completely her normal self, eating and drinking well. And very snuggly.
I've started . Her on Cystease just incase she's got a bit of stress cystitis from Penelope getting at her.

If you only put litter in one half of the tray and roll a towel or similar under the half with the litter in then the cat can urinate but most will run down to the uncat littered end and you can collect it

If they have as poor aim as my Dcats anyway.

Managed to get a sample. Nicked some dipsticks from work. It's got 2+ of protein and 4+ leucoytes in. So hopefully just a treatable infection.

Well done!
