When sniffers are bred, they do not pathfind to each-other ; they have to be forcibly pushed together in order for them to breed.
How to reproduce :
Spawn two adult sniffers (at least 2 blocks away from each-other)
Feed both sniffers torchflower seeds
The sniffers will go on with their daily routine of not hugging
