You call the cat 'it'. Has the cat been de-sexed?

"dialogue" It's fine.

I think human being especial human just whom classified to she or he - the rest (animal - stone- water - gas ...etc) we deal with it using preposition (it) , in many countries especially western animals (cats and dogs) treat as human and have all their rights such as gender to weather he or she. I think this the reason for your confusion or I am off point

"She" or "He" is better for pets, especially the ones we own, love and treat as a party of family. It's natural to call them that way. It would be actually pretty awkard to say "This is my cat. It is called Bobby" :) As for ships, I think there are some historogical reasons. Maybe because they were called by women's names or maybe because captains were attached to them as much as to their wives :p

To me, an owner would never call their pet "it" even if it was desexed. The original gender is still used: "I think he likes you." The whole issue of calling inanimate things "he" or "she" depends on the speaker's personal perception, as well as their own closeness to the thing. It has nothing to do with non-human things having a set grammatical gender in English. For example, a merchant who owns several ships for business might call each ship "it", whereas the captain and sailors would call their own ship "she" (or even "he" - it depends on the ship's "personality").
