Animals

Animals are generally neutral or hostile creatures that exist in the world of Deus Ex and Deus Ex: Invisible War. These creatures are usually either used for hostile enemies or world-building elements.

=Animals in Deus Ex=

Mutt
Mutts are the civilian dogs of Deus Ex, they are used as pets and do not attack unless attacked first. Dogs bark randomly, but it doesn't mean anything when they do.


 * A mutt can be found with the weapon mods dealer on the ship in the Hong Kong Canals.
 * A mutt can be found in the pet shop in the Wan Chai Market.
 * A named mutt called Starr can be found in the Champs-Élysées, in the arms dealer's apartment.

Pigeon
Pigeons can be found in the cities of New York City, Hong Kong and Paris. When startled by something bigger than them they fly away and after time dive down and land on the ground. Due to bad collision their feet are often below the ground while idle. Pigeons coo while idle.

Seagull
Seagulls can only be found in the coastal levels of Liberty Island at the docks and the Pasadena Ocean Lab at the surface level. Like pigeons they fly away when startled and have bad collision on their feet. Seagulls cry while idle.

Fish
Fish can be found in aquatic levels such as Liberty Island at the docks, LaGuardia Airport's dock, the Hong Kong Canals, the Cathedrale de Payens in the water under the bridge, Morgan Everett's residence aquarium, and the Pasadena Ocean Lab.


 * The beige fish has an unused puffed version, possibly intended for when the player got near.
 * The turrets in the Pasadena Ocean Lab often try to shoot the fish through the windows, leading to the area seeming more haywire.
 * Fish have no death animation and will disappear when killed.

Cat
Cats are neutral animals in Deus Ex, they try to avoid being near the player while he moves as he can step on them and kill them. Cats have a claw weapon, but it isn't used at any time. Cats can purr randomly.


 * A mole person in the Mole People Tunnels has his cat shot by the NSF for trying to escape instead of helping them find ambrosia.
 * Maggie Chow has a hostile cat in her apartment, however it does not attack as it has no weapon.
 * Morgan Everett has a pet cat in his residence.
 * Many cats are owned by Aimee in Denfert-Rochereau, Paris, where some were killed and eaten by greasels in the sewers.

Rat
Rats are vermin that are located in almost all locations in Deus Ex. Like cats they try to avoid the player to avoid being crushed by them. Trashcans and bags have a 50% chance of spawning a rat when destroyed.


 * A Red Arrow member fills the Wan Chai Tea House with rats in order to make them fail their health inspection for paying protection money to the Luminous Path instead.
 * They have an unused weapon that would let them bite enemies.
 * Rats have an unused, unfinished swimming animation.

Fly
Flies spawn around trash and dead bodies. Flies have a 10% chance of spawning around trashcans and bags upon level load and have a 20% chance to spawn around dead animals and a 10% chance of spawning around dead humans after 30 seconds.


 * Flies can be killed and spawn more blood than their body size.
 * Flies can enter water without issue.

Passive
Animals in Deus Ex: Invisible War include pigeons, cats, and rats, these are useful for the Health Leech Drone Biomod which can use the animals to give health to the player.

In Invisible War, cats are used as meals for pet greasels: "At least one whole cat per day. Live cats are the best. If you must use a dead cat, warm it up in the microwave first, then wiggle it around for the feeding. Never feed your greasel table food. It encourages bad habits. Make sure your pet has fresh water everyday."
