The shirt reads: “Cat” in a black script, with “Drool” running underneath it in blue letters that melt into drips.
The lettering does the work — the D stretches down the shirt and pools, so the word behaves like the thing it describes.
Cats are not supposed to drool. When one does it is usually because it has gone so completely limp with contentment that its face has stopped participating. If you have a cat that does this, you already know, and you have probably taken a photograph of it. For that person, and for anyone whose sense of humour is mostly made of very online animal jokes.
