Probita runs the pet insurance bureau in East Ardougne in the small building next to Aemad's Adventuring Supplies. She will insure a player's pet at a one-time cost of 500,000 coins per pet. If a player loses their pet, and it is insured by Probita, they may reclaim the pet for 1,000,000 coins. Checking what pets you have insured is a requirement for the Easy Ardougne Diary.
Probita will only insure one-off pets, most of which are exclusively obtained from bosses or by training non-combat skills. Insuring all the pets available will cost 24,000,000.
