Dempsey just let me know, in no uncertain terms, what he thinks of my singing

First topic message reminder :

I was singing quietly while Dempsey was asleep on the sofa. All of a sudden, I heard this gurgling, high pitched sound - a bit like a Basenji throwing a tantrum. Turned around, and Dempsey was howling at me! He hasn't howled in ages! So I suppose he was making a point.

Seriously though, you should hear it. It doesn't sound like a howl at all, but a strange, warbling, gurgling drone. Like a mixture between somebody gargling water and a jack hammer!
