Is this bad urine?

[Lauren22]

As from other post my older boar had recently had surgery for a bladder stone. Since he has been ok and not having many issues.
Today I found his urine like this.
I havnt found seen any problems with his urine recently and sadly he is still producing bladder sludge.
He gets 1 slice of cucumber
1 slice of pepper
1 slice of cellery daily
Is on gluten free selective food and his water is filtered.

Looks like it may be oxidised wee with a bit of poo juice mixed in. But if you’re worried you can have him seen by the vet.

Thanks, I'm probably just being over causious because of everything he's gone through recently I will keep an eye on it
