Habitat
Domesticcats primarilyliveinareasof humanhabitationandare somewhatconstrainedtodevelopedareas.Most
feral populationslive inclose proximitytocurrentorpast humansettlements.
Physical Description
There are over100 breedsof domesticcatsbut all have a verysimilarbodyshape andsize.
Adultmassrangesfrom 4.1 to 5.4 kg, and average lengthis76.2 cm.
Domesticcat have approximately244 bonesintheirbody,of whichabout30 are vertebrae
Withso many vertebrae intheirspine,catsare veryflexible andcanrotate half of theirspine 180°.
Theyare capable of jumpingfive timestheirownheightandare able to slipthroughnarrow spacesbecause
theyhave no collarbone andtheirscapulae lie mediallyontheirbody.
Each forelimb(i.e.,manus) hasfive digitsandthe hindlimbs(i.e.,pes) have four.
Theyhave retractable clawsoneach paw,whichtypicallydonotextendwhenthe animal walks.
Theyhave 26 teeththat usuallydevelopwithinthe firstyear.
Reproduction
House cats are polygynandrous,asbothmalesandfemaleshave multiple matesthroughoutthe year.
Male house catspatrol territoriesinsearchof estrusfemalesduringmatingseason.
Estrus femalescall loudlytopotentialmates,while continuallyrollingonthe ground.
Femaleshave inducedovulationwhichisstimulatedbycopulation.
Gestationrangesfrom60 to 67 days.
Femalesare reproductivelymature by6 months,andmalesare reproductivelymature by8months.
Domesticcat kittensare caredfor bytheirmothersand paternal care isvirtuallynon-existent.

Lifespan/Longevity
Captive individualsare expectedtolive forapproximately14years.

Predation
Domesticcats are occasionallypreyedonbywildpredators,suchascoyotes,foxes,mountainlions,alligators,and
manyother terrestrial predators,suchaslarge snakes,crocodiles,othercatspecies,andothercanids.
Ecosystem Roles
Domesticcats are great pestcontrol agentsfor rodentsinandaround areasof humanhabitation.
Economic Importance for Humans: Positive
Aside fromthe benefitthathumansreceive fromdomesticcatsas pets,domesticcatsare usedas model organisms
for variousbiomedical researcheffortsandhave beenusedasrodentpestcontrol agentsforthousandsof years.Itis

Economic Importance for Humans: Negative
