Just to add to the answers which Max and Katrina have given you: The word 'its' is a possessive, used for an animal or object - for example, "I complained about the hire car because its windscreen was cracked". 'Its' can also sometimes refer to a baby or very young child, if we don't know whether the infant is a boy or girl. 'It's' - with an apostrophe - is an abbreviation of both 'It is' and 'It HAS' - for example "It's been a long time" is the contracted form of "It has been a long time". One note of caution: Be aware that you will often see 'it's' used inappropriately. A growing number of native speakers are unaware of this rule, and believe that 'it's' is a possessive. There are even many reasonably well educated people who make this mistake.

"it's" = it is "its" is possesive it's (it is) a car The dog sees "its" owner.

What is the Difference between Its and It's? It's is always the abbreviation of "it is" as in "It's (= it is) a nice day, isn't it?"Its is the possessive of "it" as in, "Thatis Morton's puppy but I don't know itsname." In the second sentence, itsmeans "belonging to it"
