Кошка моргнула и снова посмотрела на меня.

Because кошка is the subject of the sentence — the cat is the one doing the actions.

In Russian, the subject normally goes in the nominative case, so:

• кошка = nominative, the cat
• кошку = accusative, the cat as a direct object

Here, the cat blinked and looked, so it must be nominative: кошка.

These are past tense feminine singular forms.

In Russian past tense, verbs agree with the subject in gender and number:

• masculine: моргнул
• feminine: моргнула
• neuter: моргнуло
• plural: моргнули

Since кошка is a feminine noun, the verbs are feminine too:

• кошка моргнула
• кошка посмотрела

This is very common in the past tense.

Because both verbs still refer to the same subject: кошка.

Russian does not need to repeat the subject if it stays the same:

• Кошка моргнула и снова посмотрела на меня.

Both actions were done by the cat, so both verbs match кошка in feminine singular past.

This is a question of aspect.

• смотреть = imperfective, focusing on the process, habit, or ongoing action
• посмотреть = perfective, focusing on a completed action or single event

So:

• кошка смотрела на меня = the cat was looking at me / looked at me for some time
• кошка посмотрела на меня = the cat looked at me, as one completed action

In this sentence, посмотрела fits because the sentence describes a sequence of completed events:

1. the cat blinked
2. then looked at me again

Again, this is about aspect.

• моргать / моргала = imperfective, repeated or ongoing blinking
• моргнуть / моргнула = perfective, one completed blink

Here the sentence describes one blink, so моргнула is the natural choice.

Compare:

• Кошка моргнула. = The cat blinked once.
• Кошка моргала. = The cat was blinking / blinked repeatedly.

Because the verb смотреть / посмотреть normally uses the preposition на when it means to look at someone or something.

So Russian says:

• смотреть на кого-то / что-то
• посмотреть на кого-то / что-то

Examples:

• смотреть на кошку = to look at the cat
• посмотреть на меня = to look at me

You generally cannot say посмотрела меня with this meaning.

Because на with смотреть / посмотреть takes the accusative case.

The pronoun я changes like this:

• nominative: я
• accusative: меня

So:

• на меня = at me

This is just the normal pattern after смотреть на.

Снова means again.

In this sentence, it modifies посмотрела:

• снова посмотрела = looked again

Russian word order is fairly flexible, so снова can often move around a bit:

• Кошка моргнула и снова посмотрела на меня.
• Кошка снова моргнула и посмотрела на меня.

But the meaning changes depending on what снова seems to attach to:

• снова посмотрела = looked again
• снова моргнула = blinked again

So in your sentence, its position clearly shows that the second action is being repeated.

They are often very close, and in many contexts both mean again.

• снова is often a bit more neutral or stylistically smoother
• опять is very common in speech and can sometimes sound a little more emotional, like again...

In this sentence, both are possible:

• Кошка моргнула и снова посмотрела на меня.
• Кошка моргнула и опять посмотрела на меня.

The first feels a bit more neutral.

Because и is joining two verbs with the same subject inside one simple sentence:

• Кошка моргнула
• и снова посмотрела на меня

Russian normally does not put a comma before и in this kind of structure.

A comma would be needed in different situations, for example between clauses with more independence or added structure, but not here.

Yes. Russian word order is more flexible than English word order.

The neutral order here is:

• Кошка моргнула и снова посмотрела на меня.

But other orders are possible for emphasis:

• На меня кошка моргнула и снова посмотрела.
• Кошка снова посмотрела на меня, моргнув.
  (this is a different structure, but similar overall idea)

Changing the order usually changes focus or style, not the basic meaning.

Still, for learners, the original version is a very natural, straightforward order.

In this sentence, it means looked at me.

Russian смотреть на can sometimes cover meanings that overlap with English look at or watch, but context matters.

Here, because the cat blinked and then looked at me again, the most natural interpretation is a brief act of directing its gaze at the speaker, not sustained watching.

If Russian wanted to emphasize ongoing watching, the imperfective смотрела на меня would be more likely.

Because the sentence describes a sequence of completed actions:

1. моргнула — blinked once
2. посмотрела — looked once

Perfective verbs are very common when narrating single finished events in order.

Using two perfective verbs together is completely normal in storytelling:

• Он встал, открыл дверь и вышел.
• Кошка моргнула и снова посмотрела на меня.

This gives a clear, event-by-event feel.

You would usually use imperfective verbs instead:

• Кошка моргала и снова смотрела на меня.

But that version is less natural as a simple narration of two single actions. It suggests repeated or ongoing behavior rather than two separate completed events.

So:

• моргнула, посмотрела = one blink, one look
• моргала, смотрела = was blinking / kept blinking, was looking / kept looking

The standard stress is:

Ко́шка моргну́ла и сно́ва посмотре́ла на меня́.

Stress matters in Russian pronunciation, especially in past tense forms and common adverbs like снова.

Not with смотреть / посмотреть in this meaning.

You need:

• смотреть на меня
• посмотреть на меня

Without на, the sentence would be ungrammatical or would no longer mean look at me.

This is one of those verb + preposition patterns that simply has to be learned as a unit: смотреть на + accusative.

Yes, usually.

Моргнуть is a perfective verb and normally means to blink once.

If you want repeated blinking, Russian usually uses the imperfective моргать:

• Кошка моргнула. = The cat blinked once.
• Кошка моргала. = The cat was blinking / kept blinking.

So learners often remember:

• моргнуть = one blink
• моргать = blinking in general or repeatedly
