A Gold Squirrel and Gold Bunny spawned next to each other.

Critterss are harmless critters that can be caught with a Bug Net and do not normally interact with the player in any other way, except in that they can be killed by both players and enemies. They have 5 health and usually serve as ambient entities in Terraria. Most critters can be summoned by means of a statue, but will otherwise spawn randomly in any environment that supports them. There are currently 41 different Critters.

On  PC,  Console,  Mobile,  Old Chinese,  tModLoader, and  tModLoader Legacy, the Gold Critters has a 1 in 150 chance of spawning instead of a normal one. These gold critters sell for 10 each. Gold critters are rare creatures which are detected by the Lifeform Analyzer. Visual identification is helped by the sparkles they emit when alive in the world.

Most naturally spawned Critterss can be caught with a Bug Net, and carried in the player's inventory (or placed in storage). If a critter caught with any Bug Net is taken from inventory and "used" (placed), it is again released into the environment at the cursor and behaves as usual.

On  PC,  Console,  Mobile,  Old Chinese,  tModLoader, and  tModLoader Legacy, Critterss can be sold to any NPC vendor.

All caught Critterss can be crafted into Critters Cages to create animated display furniture. Once crafted, the critter cannot be released. Most Critters are caged in Terrariums, however Butterflies, Fireflies and Lightning Bugs are caged in Bottles, and Goldfish are caged in Bottled Water. Bottled Fireflies and Lightning Bugs also function as valid light sources.

On  PC,  Console,  Mobile,  tModLoader, and  tModLoader Legacy, Critters spawned from statues cannot be caught with the Bug Net; attempting to do so will cause the critter to disappear in a puff of smoke.

Many caught Critters can be used as Bait with a Fishing Pole in order to go Fishing. These generally include any insect, worm, or mollusk (snail) Critters.

Most Critters will spawn in the place of enemies near NPCs. Mice, however, will generally not spawn near NPCs.

Notes

• The spawn rates and spawn caps of Critters are affected by many of the same factors as those of hostile enemies, so Water Candles, Peace Candles, Battle Potions, Calming Potions and Sunflowers will affect Critter spawns.
• Critters caught with a Bug Net when the player has a full inventory will be dropped in the world as items rather than released.
• Critters regenerate health, this can be seen by hitting them with a low damage weapon/tool, like a Copper Axe, Copper Pickaxe or a Wooden Hammer.
• Trying to release a Goldfish will cause the goldfish to be consumed.
• Once a Critter is put inside a cage, bottle, or jar, that single Critter can no longer be released, and will stay in there forever. An alternative is to simply release the critter into an enclosed area, though the Critter can then despawn if a player travels too far away.
• During a Blood Moon, Bunnies, Goldfish, and Penguins will transform into hostile enemies: Corrupt Bunnies, Corrupt Goldfish and Corrupt Penguins in a Corruption world ( and Crimtane Bunnies, Crimtane Goldfish and Vicious Penguins in a Crimson world). So it is recommended for players who are ill-equipped or have low health to either kill or capture any bunny, goldfish, or penguin in their vicinity before nightfall happens. Critters that have been placed in inventory, storage, or cages will not be affected. These same critters can be transformed manually into their corruption form by throwing Vile Powder at them, and their crimson form by throwing Vicious Powder. All Bunnies, Goldfish, and Penguins spawned from statues will transform into enemies if they are spawned during a Blood Moon. Once these critters have transformed into hostile enemies, they can no longer be caught with a Bug Net.

Tips

• With several NPCs acquired, keeping Water Candles around your suitable housing will cause more Critters to spawn, without spawning enemies.
• To find exactly how much damage an enemy does, a critter can be placed on the enemy. Critters have 0 defense and enemy damage to it will not vary unlike most situations of dealing damage. Projectiles from enemies will do varying and reduced damage to critters, so it will not work for measuring projectile damage.
• Early game, before a player can craft enough torches to place around a base, a player can use critters to alert them when an enemy is approaching.

Trivia

• Birds placed in a Terrarium peck in ascending order, the Blue Jay once, the Bird twice, the Cardinal three times and the Gold Bird four times.
• The Glowing Snail Cage emits a faint red glow, similar to the one Jellyfish Necklace does when under water.
