Ps : I recommend eating the cooked meat before it runs away

On old ark mobile you can heal carnivores quickly by putting these in your hotbar then target the dino you want to heal and spam click the cooked meat in your hotbar and it will heal 10 health per cooked meat. However when you are feeding this to a dino the stack won't automatically renew when you run out so you have to equip in your hotbar again.

On pc and ume tho you have to wait 0.25 seconds after you feed one cooked meat before you can feed another and it's a pain.
