Okay kiddo, so there's this thing called a bonsai kitten. Some people think it's a funny joke, but it's actually not real. It started as a made-up story on the internet a long time ago to try and trick people.
The story goes like this: someone would take a baby kitten, put it in a glass jar, and then force it to grow into the shape of the jar. So if the jar was shaped like a square, the kitten would grow into a square shape too. This is really mean and cruel, and thankfully it's not something that actually happens.
Real bonsai trees are special trees that are grown to be very tiny and small. They're often used for decoration and are really pretty. But we should always treat animals with kindness and love, and never try to make them grow in a way that's not natural or healthy for them. So even though bonsai kittens are make-believe and not real, it's still important to be kind to animals and treat them well.
