The mark consists of two circles side-by-side, and each circle is overlaid with a square that does not completely contain the circle. The circle and square on the left are blue, and there are four smaller light blue circles inside. The circle and square on the right are red, and there are four smaller light red circles inside. Inside the four smaller circles within each larger circle are black silhouettes of a horse, a cat, a dog, and a sheep. The bottom line of the blue square is replaced with the text "TOO COLD!!" in blue, and the bottom line of the red square is replaced with the text "TOO HOT!!" in red. In the center of the large blue circle is a white thermometer design with a blue snowflake enclosed in the circle at the bottom. In the center of the large red circle is a thermometer design in red and black, with half of a yellow sun to the left of the thermometer. Below the designs, the wording "(P.E.T.)" appears on one line, and below the wording "PET EMERGENCY TEMPERATURE ALERT SYSTEM" appears. The "E." in "(P.E.T.)" and the word "EMERGENCY" appear in red, while all other wording is blue.
