- rub his head behind his horns- scratch under his chin or behind his ears like a cat and you'll have him purring and begging you to keep petting him like a house cat
Aether:
- scratch under his chin or rub his shoulder blades- sometimes even just holding his face in your palm can make him start purring and blushing
Swiss:
- mainly purrs when cuddling you but if you rub behind his ears he'll start purring loudly- rub his back and just simply holding his hand will make him purr and wag his tail happily
Rain:
- praise him and hold his hand while he lays on your chest and he'll start purring really loud and try to hide his blushing face in your neck- playing with his hair is mainly how to get him to purr
Mountain:
- give him a kiss and his tail will start wagging and if you kiss him and rub behind his horns he'll purr louder than any of the other ghouls- blushes and starts purring while you rub his back bit this is his way of asking for more
