This guide will show you how to make a simple bed for your pet in Minecraft PE 0.13.0 +. Enjoy! ?
Step 1: Materials
You will need 4 slabs of your choice, (I chose acacia), 8 wooden trapdoors, and a tamed cat or dog.
Make a 2 by 2 square of slabs.
Surround the square of slabs with trapdoors so it looks like the picture.
Put your pet in the completed bed.
This is what it looks like with a cat.
