“My child will not eat fish. What can I replace it with?”/“A cat. Cats love fish.”

A joke about meal replacements became popular in September 2020 and has been printed on several images:
 
Q: My child will not eat fish. What can I replace it with?
A: A cat. Cats love fish.
 
The original speaker wanted a meal replacement, not a child replacement. It’s not known who authored the joke.
