I think usually cats don't use their anal glends in the way that they "spray" the fluid onto things. Usually a small amount of anal glend fluid covers the poo, it's released from the glends while the cat is presssing.

It can happen that - for example when a cat has diarrhea and doesn't need to press so hard - that too much fluid remains in the glend which can lead to imflammation. Maybe this is what Raven has. But I'm sure the vet will find out.
