Ferret
Ferret is one of the 12 companion pets in Loot Grinder, the free medieval idle clicker.
About
Ferrets keep vermin under control and improve food storage efficiency throughout the kingdom.
Bonus
Once fully bonded, Ferret grants a permanent +2% loot per second.
How to bond
Adopt Ferret for 360K loot, then pet it as it strolls across your kingdom — 25 cares fully bond it and lock in the bonus for good.
Why it’s useful
A companion you’ve fully bonded never needs tending again — it’s pure, permanent loot-per-second layered over everything else your kingdom earns.
