Como dizer "(se) refestelar" em inglês

Curiously, cats can be referred in some ways:

My cat rolled in mud for pleasure. It/She got all dirty.
My cat rolled in mud for pleasure. He/she/got all dirty.

Well, when we talk about pets, many Grammarians/grammarists would accept referring as "she", regardless of gender. It's a privilege for pets, specially cats.
Many would prefer "he" (should the cat be a male cat), specially iif his owner (or "his master" - as per old ways), or if your language is like Portuguese it spill over to your English speaking (and it's okay).
Even to English speakers it boils to the language preferences of the owner (of the pet).

Of course, other than that context (to a reader) would give clues:
Robert's cat can recognise its master's voice (speaker does not know whether the cat is male or female)

Robert's cat can recognise his master's voice (knows that it's a tom cat)

Note that in "Tom and Jerry", certainly Tom is a tom cat! LOL.

These examples were taken from -

E-pronouns-he-and-she-for-animals

Your cat could be also called he-cat (as opposed to "she-cat"). By the way, I said a tom cat is a male cat (a tomcat a fighter plane, certainly inspired by the tom cats, or Tom from Tom and Jerry).
Well, you would say, Tom a male cat, and a female one? It would be a Tabby Cat (that means a female cat, but also could refer to a cat of any gender 'wearing stripes'.

By the way, if you have a couple of cats how do you tell the female from the male?
...you figure out by the look on their faces, the female one will have a smile on her face?
Just kidding guys! It will be the more talkative one... Or meowative!

Meu gato (sic) se refestelou toda na lama. Ficou toda suja.

My cat wallowed in mud. It/She was a mess.

My cat rolled in mud for pleasure. It/She got all dirty.

Corrigi. Eu esqueci que o sujeito era masculino xD
