Cats are wired to hide discomfort, so changes can go unnoticed for a while. The litter box is one of the few places you can see what's going on, without stressing your cat or changing their routine.
Open a bag and sprinkle it on top of your clean litter.
Your cat uses the box like normal. Nothing new to get used to.
Compare it with the color chart each time you scoop.
The exact colors are on the chart in each pack. The rule of thumb is the same for both types.
Nothing to do.
Look again at your next scoop.
Or any change in your cat's behavior: call your vet and tell them what you saw.
