These kinds of visual puzzles are great because they test how carefully we observe details. Some people only spot the largest animal first, while others quickly notice the smaller ones hidden inside. It all depends on how your brain processes shapes, outlines, and negative space.
Take your time and look closely before checking the answer. Try to count every animal you can see from the biggest shape to the smallest one hidden inside.
Answer: 5 animals — horse, cow, pig, rabbit, and cat.
