The teams at AFB International and Integral Molecular studied the behavior of two different
cat bitter taste receptors in cell - based experiments, investigating their responsiveness to bitter compounds, and comparing these to the human versions of these receptors.
Like its human counterpart,
the cat bitter taste receptor Tas2r43 was activated by bitter compounds aloin (found in the aloe plant) and denatonium (used to deter children and pets from consuming chemicals such as antifreeze) but responded differently to the compounds.

The team also found that probenecid, a known inhibitor of human
bitter taste receptors, also worked on both
cat taste receptors, preventing stimulation when in the presence of PTC, aloin and denatonium.
According to new research from the Monell Center,
cats have at least seven functional
bitter taste receptors.
Despite this,
cats, like dogs, possess
taste receptors for
bitter.
