May pusa rin kami, at bihira siyang lumabas.

In this sentence, may means something like there is/there are or have.

So:

• May pusa kami = We have a cat
• More literally, it is like There is a cat on our side / in our household

This is a very common way to express possession in Filipino.

You may also see related forms like mayroon or meron.

After may, the noun usually appears without ang.

So you say:

• may pusa
• may bahay
• may problema

Not:

• may ang pusa

That is just how this construction works. May introduces the existence of something, and the noun that follows is normally unmarked.

Kami means we, but it is the exclusive form.

That means:

• kami = we, but not you
• tayo = we, including you

So May pusa rin kami means the speaker and their group have a cat, but the listener is not included in that we.

Rin means also or too.

Rin and din mean the same thing. The choice is mostly based on sound:

• use rin after words ending in a vowel, w, or y
• use din after most consonants

Since pusa ends in a vowel sound, rin is the expected form:

• May pusa rin kami

In casual speech, you may sometimes hear variation, but this is the standard guideline.

Filipino often puts the predicate first.

So May pusa rin kami is the natural, everyday order.

A more English-like order is possible, such as:

• Kami rin ay may pusa

But that sounds more emphatic, contrastive, or formal. For ordinary conversation, May pusa rin kami is the most natural.

Siyang is siya plus the linker -ng.

• siya + -ng = siyang

This linker helps connect siya to the following word or phrase. In sentences like this, it is very common and natural:

• bihira siyang lumabas
• ayaw niyang umalis
• nakita ko siyang tumakbo

So siyang is not a different pronoun; it is just siya in a linked form.

Bihira basically means rare, infrequent, or seldom.

In this sentence, it works like rarely in English:

• Bihira siyang lumabas = He/She rarely goes out

So even though bihira can look adjective-like, in this kind of sentence it functions very naturally as a frequency word.

Lumabas comes from the root labas, which has the idea of outside or out.

The verb form lumabas is made with -um-, a very common verb marker:

• root: labas
• verb: lumabas

Its basic meaning is to go out, come out, or go outside, depending on context.

That is a very common learner question.

Yes, lumabas can mean went out in other contexts. But Filipino verbs do not work exactly like English tense forms. They focus more on aspect, and the surrounding words often tell you how to understand the action.

Here, bihira gives the whole clause a habitual meaning:

• bihira siyang lumabas = she/he rarely goes out

So even though lumabas can look like a past form to an English speaker, the full sentence is understood as a general habit, not one finished event.

Yes. In Filipino, siya can be used for an animal, especially a pet.

English makes a strong distinction between:

• he/she
• it

Filipino does not divide things in exactly the same way. For pets or animals with some personal importance, siya sounds very natural.

So in this sentence, using siya for the cat is completely normal.
