A good thing that they have a diagnosis, but why cat slaves don't get their owners neutered is beyond me.Our next door neighbour, a young single mum with a severely handicapped kid, got herself a kitten around a years ago (after a previous kitten was handed back to the original owner when she mistook a cat's loud purring as growling and thought it was going to go for her ). Anyhow, this week, her cat has been showing some concerning activities such as attacking it's own tail and growling (proper growling as opposed to loud purring) at her, so she took it to the vets. They came up with the diagnosis of feline hyperesthesia syndrome (Feline hyperesthesia syndrome - Wikipedia), they gave her a load of pills to see if that would sort it. 2 days later, she was asked to bring her back in and now the diagnosis (after having tests on Monday) is Epilepsy and being in season at the same time is causing her to behave as mentioned above. Treatment is now going to include said kitten getting speyed and medication for epilepsy.
