Separate baby-pet care from servitor combat restrictions.
Baby Buffalo, Baby Cougar and Baby Kookaburra eat Baby Spice. These domestic pets have limited combat ability. Little Harness is their baby-pet armor and is sold by Pet Managers.
The C4 rule leaves a dead pet as a corpse for up to 20 minutes, after which both pet and control item disappear. Logging out does not resurrect it or safely store it alive. A server crash has separate handling; it is not the same as a personal disconnect.
The C5 change prevents unsummoning a servitor in combat. Resolve the combat state first. This wording concerns servitors; it does not establish an identical rule for every pet.
