After buying all pets & reaching near late-game levels/quest there is no real reason to interact with Pets on a daily or even weekly basis.
Just as the Farm Animals are pet daily to raise their level maybe a similar feature/type of interaction could be added for Pets.
Instead of level increase maybe they could yield a few additional found items for that hour or perhaps a specific item of our choice.
Even if only 1 pet could be interacted with per hour/day/week I feel it’d be a nice addition, the ability could be released as a Perk/Farm Upgrade for balance I suppose.
Please consider, thanks so much.
