Minor pets are small collectible animals, which include lizards, snakes, rodents, turtles, small birds, and large birds. Minor pets are featured in The Sims 3: Pets. Common minor pets can be purchased, while rarer pets must be caught in the wild. Minor pets can be set free if a Sim cannot properly care for them. If kept in a Sim's inventory for too long, minor pets can escape. Birds can be killed by cats when they're placed on bird cage or bird tree. Unlike the main pets, these pets can be spotted by the Collection Helper lifetime reward.
