HOW ??

The question is a riddle.

You have:

• 3 cows: $3\times 4=12$ legs
• 2 dogs: $2\times 4=8$ legs
• 1 cat: $1\times 4=4$ legs

Total legs from animals: $12+8+4=24$ legs.

However, the riddle asks “How many legs do you have?” If we assume you have 2 legs, the total would be $24+2=26$ legs.

So, the answer is 26 legs.
