My husband' s cardiologist is a facc. We are moving, and when we asked if he knew of a good one in nc, he said the facc would be good to look fot, because they have sat for the test nand keep current. That being said, he also told us some older drs. Have not sat for the test and are better than some facc ones.
Deathwatch beetle. Deathwatch beetle (Xestobium rufovillosum), an anobiid, or borer insect, of the family Anobiidae (insect order Coleoptera) that makes a ticking or clicking sound by bumping its head or jaws against the sides of the tunnels as it bores in old furniture and wood.
Others have noted that the clicking noise is similar to the sounds that a cat makes as she delivers a deadly neck bite to a prey animal. Maybe jaw clicking is just your kitty's way of keeping the lid on her nearly uncontrollable excitement as she feasts her eyes on glorious food she can't reach.
