63 Rat Puns That Are Squeakingly Funny

Rats don’t get enough credit in the pun world. Dogs, cats, fish, they’ve all been done to death. But rats? Rats have “rat” right there in like forty English words, they gnaw on everything, they’ve got tails, they live in mazes, and one of them became a Pixar chef. The pun potential is honestly overwhelming, and I’ve been sitting on this list for weeks.

1. The Warm-Up

You’re looking mighty rat-tractive today.

2. The Classic

Why did the rat study philosophy? He wanted to be a rat-ional thinker.

3.

I smell a rat, and honestly, it’s me. I held my pet rat for twenty minutes and now my hoodie smells like cedar shavings and regret.

4. Instagram-Ready

Life’s a rat race, but I look good running. 🐀

5.

Don’t gnaw-ry, be happy.

(I’m not sorry. Okay, I’m a little sorry.)

6.

What do you call a rat who won’t stop hoarding vintage magazines?

A pack rat-tress. Or just my aunt. Same thing.

7.

“Chew be or not chew be”, that is the question every rat asks before biting through your phone charger at 3 AM.

8.

This cheese is absolutely rat-tisfying.

Okay wait, I need to acknowledge something. The research material I started with had about fifteen variations of “rat-tling good [noun]” and I refuse to use more than two of them. Nobody needs “a rat-tling good appetite” AND “a rat-tling good memory” AND “a rat-tling good bargain.” We’re better than that. Mostly.

9. One I’m Actually Proud Of

My rat got into the spice cabinet and now he’s making ratatouille. I’m not even mad. I’m rat-her impressed, actually. He’s been watching Pixar films behind my back and I think he’s more cultured than I am. The little guy even did a flavor check with his eyes closed. I’ve never felt so outclassed by a creature that weighs eleven ounces.

10.

Scurry up, we’re gonna be late!

11.

Why did the rat break up with the mouse? She said he had a rat-titude problem.

12.

• Say cheese! 🧀
• This is a gouda idea.
• I’m feeling grate!

(The cheese pun triple-threat. Had to get them all out at once like ripping off a band-aid.)

13.

Don’t rat me out.

14.

I told my friend her new apartment looked like a rat’s nest and she said “that’s the aesthetic.” Fair enough.

15. Subtitle: This One’s Niche

What do you call a rat who’s really into Baroque architecture? A rodent of the Corinthian order.

(If you got that one without Googling, I respect you deeply.)

16.

He’s a real rat-fink.

Does anyone even say “rat-fink” anymore? My dad used to say it all the time. It’s from the ’60s, I think. Ed “Big Daddy” Roth made those rat-fink hot rod characters. Anyway. Moving on.

17.

That’s a rat-her bold move, Cotton.

18.

Why did the rat go to the dentist? He had a gnaw-ty habit he couldn’t break.

19. Genuinely Good, Send This to Someone

You’re a-maze-ing 🐀🧀

Works as a text. Works as a Valentine. Works as a caption for literally any photo of a pet rat in a cardboard maze, which is a very specific genre of content I consume too much of.

20.

Don’t be so rodent-less.

(Ruthless → rodent-less. Yeah, it’s a stretch. I know. I KNOW.)

21.

I asked the rat if he wanted to hear a joke. He said “tell me a tail.”

22.

Rats! I forgot my cheese again.

23. The Fancy One

I’m going to rat-ify this agreement.

This pun works best if you’re a lawyer or a senator. Or a very bureaucratic rat. The Venn diagram of those three groups is more of a circle than you’d think.

24.

Don’t be a copy-cat. Be a copy-rat.

25.

What do you call a rat who loves Shakespeare? The Bard of Aver-gnaw.

(This is terrible. I’m including it because I spent way too long on it to delete it now.)

26.

He’s got a real bite to his personality.

27. The Obscure Science One

Did you know rats exhibit something called “Zucker” genetics in obesity research? I guess you could say some rats are born to be… thick-skinned.

Okay that’s barely a pun and more of a lab rat deep cut. The Zucker rat is an actual research model. Google it. I’m not making this up. The pun is weak but the fact is real, and sometimes that’s enough.

28.

The drummer played a rat-a-tat beat and the rats started moshing.

29.

I’m feeling a bit ratty today. Don’t test me.

30. My Personal Favorite of This Entire List

What’s a rat’s favorite movie genre?

Gor-gnaw.

LISTEN. “Gore” + “gnaw” = “gor-gnaw.” It sounds like nothing in isolation but if you say “I’m really into gor-gnaw films” out loud it works perfectly and I will die on this hill. This is peak wordplay. My friends disagree. My friends are wrong.

31.

This situation is getting rat-ical.

32.

After the rain, I looked like a drowned rat. Which is unfair to drowned rats, at least they have an excuse.

33.

• He’s a real street rat.
• She’s got that sewer-side hustle.
• They’re living that underground lifestyle.

(That middle one is dark. Moving on quickly.)

34.

Don’t get your tail in a twist.

35. For the Gamers

Why do rats make great speedrunners? They’ve been running mazes since before it was cool. Literal frame-perfect navigation. No glitches needed.

36.

I gnaw what you mean.

37.

This is a rat trap and I walked right into it. Story of my life, tbh.

38.

What did the rat say to the cat? “You’ve gotta be kitten me, I’m the one with all the puns.”

Side note: I’ve been writing rat puns for about two hours now and I just realized my actual pet rat has been staring at me from her cage this whole time. She looks unimpressed. She’s right to be.

39.

I’m feeling a bit gnaw-stalgic for the old days.

40. Another Favorite

What do you call a rat who works in government?

A bureauc-rat.

This one’s clean, it’s obvious, and somehow NOBODY ever uses it. It was right there the whole time! Bureauc-rat! It’s perfect! I feel like I discovered fire except the fire was always burning and I just refused to look at it.

41.

He’s squeaky clean. Suspiciously so.

42.

This movie is rat-tastic. Specifically Ratatouille. Always Ratatouille.

43.

Don’t let the cat out of the bag, or the rat out of the cage. Both cause chaos, but only one knocks over your spice rack.

44. The Music Nerd One

What’s a rat’s favorite Beethoven piece? The Moonlight Son-gnaw-ta.

(Ngl, I had to look up how to spell “sonata” to make sure this even worked phonetically. It kinda does? Squint and it works.)

45.

I’m on your tail!

46.

He’s a real nest-case.

This one is bad. Basket case → nest-case. The logic is there but the sound isn’t. I’m keeping it in because this list needs its villains.

47.

I’m feeling rodent-ic today. 💕🐀

Caption-worthy. Send it to someone you love. Or someone who owns rats. Ideally both.

48.

Why did the rat cross the road? Because the chicken was taking too long and rats don’t wait for anybody.

49. The History Nerd Deep Cut

What do you call a rat who survived the Black Plague?

Bubonic and confident.

Technically the fleas were the vector, not the rats themselves, and I WILL get emails about this. The rats were hosts. I know. Epidemiology Twitter, please stand down.

50.

This is a rat-tling good story and I won’t apologize for using “rat-tling” exactly once.

51.

What did the rat write on his dating profile? “Looking for someone who appreciates a long tail and good cheese.”

52.

He’s a real Rat Pack member. Sinatra energy. Whiskers and all.

53.

I’m going to rat-tle some cages.

54. The Stretch That Barely Counts

What do you call a rat at a karaoke bar?

A mic-rodent.

(Microphone + rodent. Look, I never said they’d ALL be good. Some of these are here out of obligation. This is one of them.)

55.

• Don’t be so crumb-y.
• That’s a half-baked idea.
• You’re really on a roll.

The bread-adjacent rat pun cluster. Because rats love crumbs and I love low-hanging fruit.

56.

He’s got that rat-pack-titude. He walks into a room and everyone knows who’s in charge. It’s the confidence of a creature who’s survived New York City’s subway system.

57.

What do you call a philosophical rat? A rodent-ial existentialist.

(This is my second-favorite on the list. “Rodential” sounds like it could be a real academic word and I think that’s what makes it land.)

58.

I’m feeling a bit rat-tled by the news. But when am I not.

59.

What’s a rat’s favorite type of math? Algeb-rat.

60. The Closer

My rat just looked at this entire blog post, twitched her whiskers once, and went back to sleep. That’s the most honest review I’ve ever gotten.

61.

Rat-er than complain, I’ll just keep making puns.

62.

What instrument does a rat play? The mouse-organ.

(A harmonium is literally called a mouth organ but I changed it to mouse and honestly? This pun is held together with tape and hope. Bad pun. No regrets.)

63.

You’ve been rat-her patient reading all of these.

If you’ve made it this far, you’re either a rat person, a pun person, or someone who’s supposed to be doing something else right now. Either way, same. I’ve got sixty-something rat puns in my browser history and a real rat who still won’t look at me. Worth it.
