He lived with us almost all his life (we adopted him from an "accidental litter" together with his brother who passed away last summer) and has been a good comrade to all other rats he has hung out with, outliving many of them.

Looked like a chill dude.

I'm sorry pal. Losing any pet hurts. Sending love your way.

Three years is a good age for a rat, I’m sure he felt very loved

Love his little hammock, rest in peace.

That's like rat methusala. Here's to a real one. They lived long in a profession where most rats die young

Looked like a sweetie, goodnight little buddy.

Sweet Cookie, I’m glad you got to be loved and play with your rat buds. Rest well little guy

Cookie looked like a sweetheart

My heart goes out to you in these times

He looks incredibly cute, and will be missed ;-;

What a cute little rat! They're really the sweetest-looking pets.

First one to greet your rat friend on the other side

Thank you for your service Cookie. 🙏

What a sweet little guy. Three years is a real blessing. I still miss my two rats. He looks like he had a wonderful life.

i love the little hammock. my rat, Stretch, only made it a year (he got a tumor and had to put him down). never got another after that.

they are so smart one day we'll life extend them and they'll just inherit our civilization

Congratulations to Cookie on living a full happy lil rat life. Such a tragedy that they're so short-lived.

I imagine he had a good life with you. Rest in peace, Cookie. I'm sure you made the world a little bit better.

Farewell, little comrade! I hope you enjoyed your (all too short) life!

I also have an old rat. They are cool little dudes.

rest in power, comrade rodent

Rest well cookie

Better than a gerbil, those shits are meaner than geese

Oh you sweet, poor thing, I've lost so many myself, and it always hurts so much. Rats don't live nearly long enough for all the love and affection they give. My heart aches for you.
