Pet perks are not something we would ever consider adding, these are things you will find on custom rsps, something that Battlescape is not. Battlescape is an OSRS focused economy server.
Pets are simply a small commodity to show and flex over others, they are also easily obtainable for free trade accounts being in the Bond store.
Adding any form of boosts to pets only upsets the game in the long run, makes group bosses much more unbalanced, any boosts and other bonuses can all be obtained though Relics and Rank systems.
The suggestion of Pets having Perks is not something we are going to add or consider.
