When the player enters the bed the cat will wander around instead of getting into the bed and laying in it with the player. The player does still get the gifts from there cats but I love the animation that comes along with it with the cat entering the bed and laying down in the bed with the player.
I have over 20 cats in my relatively small base. Ive slept in it 4 times now. The first time is when all my cats were sitting so I just assumed that they don’t gift when sitting. The last 3 times I stood up all 20 of my cats and then slept and still not one gift was given and not one cat has slept with me.
I am on iPad Pro 12.9” Gen 1 on iPadOS 13.4 with Minecraft 1.14.30.
