Chemistry Cat
Chemistry Cat is a 2011 advice animal image macro featuring a bespectacled cat in a bow-tie captioned with science puns, especially wordplay built on periodic-table element symbols. The series took off in late July 2011 after templates hit the major meme generators and got picked up by Huffington Post and other internet-culture blogs.
Overview
Chemistry Cat, sometimes called Science Cat, is an advice animal image macro of a bespectacled cat wearing a bow-tie, captioned with jokes about science and the periodic table of elements1. The gags typically use atomic symbols as part of the punchline, like "Cats are composed of iron, lithium and neon... FeLiNe."
The photo shows a tabby seated in front of what looks like a chalkboard, giving it a professorial look that fits the joke format. Many of the puns predate the macro itself, drawing from chemistry gags long circulated in K-12 education and periodic-table lessons4.

How to Use This Meme
The template typically places a science-themed setup at the top of the image and a punchline at the bottom, often using atomic symbols to spell out a word1. A common convention is element-based wordplay, like combining iron (Fe), lithium (Li), and neon (Ne) to spell "FeLiNe." Physics and biology gags show up too, but chemistry jokes built on the periodic table are the core of the format.
