"I was like: 'but where is that dog's body gone?'" one wrote.
"We may not like it, but this is what CatDog really looks like," another joked.
A third added: "I thought it was about how it looked like it was a decapitated dog head on a roof, but the dog was really just resting its head on the edge while sitting on a lower platform. I was thinking. 'it's obvious the dog is just sitting below the roof edge. How are you confused? It's so obvious!.....oh'."
Someone else quipped that cats need to be called out on their bull**** and wrote: "Whenever I see a stray cat snooping/sneaking around I like to 'pspspspspsp', point directly at them, tell them I see them and that they are not as sneaky as they think they are being. You have to call cats out on their bull**ht sometimes.
This wouldn't be the only time that animals have become the subject of mind-bending illusions.
