Hi, I've had cats all my life but have not come across this before.
We "homed" a lovely boy about 6 weeks ago that had been an abandoned stray for a couple of years. He had been treated for a flea allergy as his "lower half" was bald. He is a bag of nerves but is slowly coming to trust us and is affectionate.
However if anything upsets him, he starts to over groom taking out great lumps of his fur and grazing his skin.
I've arranged a home visit with the vet next week, but wondered if any of you have had experience of this.
I have been using the Feliway defuser but although I'm sure it helps its obviously not enough!
