“Leather is like a cool dragon’s skin. Don’t make it sad.”

Don’t splash water on it. It hates baths. Just wipe it with a sleepy cloth (aka, soft and dry).
If it gets dirty, whisper to it and use a damp cloth very gently.
No sunbathing! Leather gets grumpy in hot places.
Don’t fold it like laundry, it likes to stretch out and chill.
Give it a cuddle with leather cream once in a while. Like giving it a milkshake
