Highlighting Misleading Headlines
Humans seem want to know two things about their pets: WHAT ARE THEY THINKING? and DOES (S)HE UNDERSTAND ME? This desperation leads to endless click-bait about what exactly is going on in our fuzzy friends' minds.
What is my cat thinking?
A new device (that has no peer-reviewed testing that I can find) - basically a fancy collar that measures activity - claims to tell you if your cat is playful (OK, that I believe), or happy or annoyed. The collar will measure heart rate and temperature (how accurately?), but consumers should know that we have no accepted measures of "happiness" or "annoyance" in pets. I feel pretty confident in saying this collar cannot tell you what your cat is thinking. BUYER BEWARE!
