I went to adopt a hamster and ended up bringing home a different species: a rat, or maybe a mouse.

No matter how cute it is, [Should I raise a rat?] initially, I was resistant

to the idea of raising a rat. [Panda mouse] But hearing that these little guys only live

for about two years, and that this species is used as lab animals, I felt so bad that I had to take one home.

Since I brought it home, [Shall I do it too?] I planned to conduct an experiment with this lab rat.

[Plan to raise it in the wild for two years] What would happen if I let this rat live in nature?

Oh, by the way, I haven't introduced myself yet. Actually, I was born

[I live in a botanical garden] as the son of a botanical garden. I'm trying to turn our garden into a zoo,

so I need your subscriptions and likes. [If I ring the bell, pigeons come to eat]

[Day 1 of adoption] Upon closer inspection, this little one was much smaller and cuter than I thought.

[Too small and adorable...] But no matter how small he was, [Too small insect collecting container] it was too small to raise him here.

So, I discovered an aquarium neglected and abandoned in a corner of the botanical garden.

It's practically an antique, but for starters, [First cage] I decided to raise him in this fish tank.

Now, this tank has been equipped with a cabin surrounded by a bamboo forest, a wheel for him to run around endlessly,

and a burrow where he can be monitored 24 hours a day. It has transformed into our first nature-themed habitat.

So now, this cute panda mouse is seeing nature for the first time in its life. At first, of course,

he was naturally on high alert. He hid in a corner, explored and tasted every rock and leaf.

I named him "Panda", hoping he would become the next Fu Bao, but his behavior was nothing short of that of a country roadside rat.

[Just a real rat] [(My mom doesn't understand)]
There are so many rats around here.

Why do you pay money to bring a rat home? Honey, just go catch one for your son.

So the rat began using the wheel and eating, washing, and he slept well in the burrow.

[Day 5 of adoption] I noticed his strange behavior. The guy kept blocking the entrance of the artificial burrow.

Ah, this one is indeed a male with two grapes. [Maximum security]
Anyway, he kept blocking it off,

and when I unblocked it, he would block it again and I would unblock it. Block,

unblock; after repeating this, the cage became super messy. And it was time to clean the cage.

[What's the problem?]
I was curious about why the rat was behaving this way. Most people raised them in bedding,

and I raised him in dirt, so there was really nowhere to ask for advice. So I just thought maybe he was lonely,

and I was a crazy one. I brought a female rat. [Day 14 of Adoption]

Ah well, this messed up. [King and queen of breeding]
Looking back, I was just crazy.

Unaware that I was insane, I conducted a meet-up for the two lifelong singles on my palm,

and they seemed to like each other; the atmosphere was hot, giving off that vibe.

so I emptied the tank and slightly remodeled it. For some reason,

a sprout that wasn't planted was growing there, reminding me of the saying

"You reap what you sow," so I left the sprout-like ones in the remodeled cage

and put the two rats in. I later learned that the male's testicles

get swollen when the female is in heat. My female rat was in heat.

Unable to calm his excitement, he rushed in, got rejected, rushed in, got kicked out repeatedly.

Wasting a day like that, the male suddenly changed his strategy.

Like the saying that females get drunk on the atmosphere,

when the female was digging a burrow, the male didn't just watch but entered to help,

starting to assist her. That made the female inevitably rely on him.

But she really didn't have an alternative. Thus, while the male appealed to the female, the once remodeled enclosure

was wrecked again, but it was obvious to the eye that they had grown close. After showing such touching scenes,

these two paired up. Watching that scene made me feel proud that the rats wouldn't be lonely anymore,

but these animals just kept mating, disturbing the night with their squeaking,

Darn creatures. [Day 25 of Adoption]
After their burning time passed, they showed a very affectionate demeanor

towards each other. [Must have been really hot!]
But the enclosure was completely wrecked.

I didn't touch it, fearing I might disturb their mating. But assuming she was pregnant, [Cleaning is impossible if late]
I had to clean and make the habitat cleaner

and more comfortable right away. I suspected she was pregnant because [Drooling all over]
this female rat had a much better appetite.

[Day 28 of Adoption]
Anyway, I immediately remodeled the enclosure. [Just digging, guys!]
Since they kept digging burrows in the dirt,

they wouldn't use the wheel. [Wheel disappeared]
So I decided to remove the wheel and instead laid down more dirt.

These guys might look trivial, but being rodents, they need to grind their teeth. So by inserting a vertical structure

that could serve as a playground, I managed to kill two birds with one stone. However, I never saw them grinding their teeth.

Finally, I added more plants and finished by watering them. Two days later, [Day 30 of Adoption]
I gifted the rats their new home

as a honeymoon spot. The rats began climbing the trees and were fascinated by the plants, seemingly enjoying a passionate honeymoon life,

but upon closer inspection, most of it was fighting. The female was beating up the male, and the male just dug a burrow.

These critters just dig. They are crazy for burrows. So I tried to think of a way

to stop them from fighting. They liked dried mealworms as snacks, and just then, the botanical garden had plenty of mealworms,

[Robbing the botanical garden!]
so I just stole them and used them to enrich their honeymoon home.

[Day 38 of Adoption]
When these critters heard the lid open, they would come out of their burrow to greet me.

[Peekaboo]
Since they got used to coming out and taking the dried mealworms,

it seemed like they recognized what mealworms looked like pretty well. [Terror begins]
So, I just released mealworms into the enclosure.

I assumed they would hunt whenever they were hungry, and ultimately, they could live more like wild rats.

But soon, the mealworms [Successful infiltration]
started crawling into their burrows. I freaked out,

thinking, what if they crawled into their ears? So, I caught the mealworms one by one again,

gathered them in a glass bowl, and called the rats over again, but what the heck?

That's when the female rat made her first successful hunt. She turned her back to me and began eating the mealworms deliciously.

Then, the male suddenly appeared and slowly approached the female, [First Successful Snatching]
snatching the mealworm she was holding.

She chased after him belatedly, but the male had already run off with it and was eating.

[Deserved to be beaten]
I guess I understood why this guy got beaten up. Anyway, the female gave up chasing

and soon started hunting again. Right beside the cabbage on the brink of death, she began eating mealworms again.

[What's that behind?] He hunted again what the female was eating. [Mind's gone mad]
Stupid creature.

Thus, the female continued hunting and the male continued snatching endlessly. [Day 40 of Adoption]
The plants in the enclosure were nearly gone.

[Hide well, your hair might show]
The creatures didn't show themselves on the surface for a while.

The sprout-like plant [Wasn't even planted but grew, right?]
grew well on its own.

But anyway, since they weren't showing up for a while, I thought, "They're not dead, right?" I thought these critters might have died,

but thankfully, when I checked, I found them busily digging burrows! 

After completing their underground paradise, they started bringing cut plant leaves to their burrows. I'll take you

to see how they block the moisture coming up from the ground. They were quite smart in this regard.  The cabbages were being eaten by them.

Feeling pity for these barely surviving creatures, I decided to undertake a cabbage rescue operation. 

Cabbage rescue operation! After removing the cabbage from the enclosure and planting a new one, while the critters ate the new one,

the rescued cabbage would regrow its leaves. By repeatedly replacing them each time, perhaps I could always have fresh cabbage?

No, you can't! It was just silly. It doesn't make any sense.  Shall I try farming? Maybe if I grew cabbage, it could work.

Then, the critters began to also pluck at the roots of the cabbage. Reading articles about crops failing because of rats

started to make sense to me. Darned creatures! Anyway, I quickly gave up on the dying cabbage,

Day 45 of Adoption! And on the 45th day, I took out the female,

and you could clearly see her swollen belly.  Even compared to the male, her belly was extremely swollen. Seeing this,

I guessed she was definitely going to give birth and tried to remodel the enclosure

for optimized parenting, but then I found that a plant I had planted contained toxins. Beware, *Sorghum × drummondii*! Although it's toxic to cats,

it seemed fine for rats. But I removed it just in case. Feeling the space was too small,

[Second-floor expansion completed]
I remodeled the enclosure to a two-story design, doubling the area.

Proudly, I shared this revolutionary idea with my friend who was helping me film.  You said she is pregnant.

Can she go downstairs to drink water and eat, then come back upstairs? Is it possible? Why are you just mentioning this now?

This guy is one year older than me. [You and I are friends!]
And he said we would become friends while drinking.

So I'll say what I feel about him: totally nuts! So, I immediately restored everything back to normal,

adding many structures. I created an environment where I could immediately check if anything happened. I put some dirt in.

"What if they get stressed?" [No worries]
is useless thinking. They're just crazy for burrows.

[Day 53 of Adoption]
After some more time, I thought I heard a sparrow in the morning,

[Two seconds before ASMR starts]
but it was the rat that had successfully given birth. [One second before ASMR ends]

But checking it out, [Hmm... Quite a lot...]
there were quite a few babies.
