It’s very simple really, being different provides a balance which allows them to be mutually complete and that enables both to serve as each other’s better half. In other words, a yin to their yang.
Alright, you know what? I lied. They do it because they’re just so cuuute!

Happy catpybara!
Is that what that is? I keep mixing them and nutria’s up.
Easy way to tell them apart: nutrias have tails, capybaras don’t!
Oh my gawd! This may be the sweetest thing ever! I actually squealed when I saw it… I love capys, but didn’t know they like kittehs. Eeeeeeeeeeee!
Even R.O.U.S.’s squee over kitties!
This is a much more positive cat-plays-with-rodent scene than most I’ve seen.
Looks like the rodent is playing with the cat instead of the other way around
They’re friends ’cause this is one rodent who is too big for the cat to eat.
What is that big animal with the cat called?
it’s called a CAPYBARA !!! :-0
Capybaras look like giant guinea pigs to me.
That’s cause they are a close relative of guinea pigs, and belong to the same family!

Eeeenterestingk. Thanks, mie!
*rubbing my eyes*
Capybara, native to South America, the world’s largest species of rodent. I’ve seen them in zoos, but I have no idea of their personalities. But domestic cats can make friends with almost anything.
And will do so at the slightest provocation!
Where? How? What the…? Who cares when the results are this cute.
Oh alright. I lied. They just do it because they are tooo cute!
I just can’t. That’s too cute.
In case it hasn’t already been posted (I don’t think it has), this DEFINITELY calls for the posting of the video I submitted awhile back of sleeping capybara skritches!!
Omg, the capy has his own blog, gianthamster.com. It’s super funny and really well written. Woohoo what a find!
It is fantastic!
That is all.
Thanks for the Paula Abdul music video … I needed that!
Thanks for saving me the effort! First thing I thought of! Right after Whiskey Tango Foxtrot…
Now my day is complete ! thank you C.O. !!!!
If my cats see this I will have to get them their own capybara, ya know. Or will I have get three, one for each cat? (Not they they are spoiled, no way, no siree Bob!)
Of course, your dear sweet kitties are not spoiled, amyliz
You’re right. Amyliz’s kittehs aren’t spoiled. Amyliz however, is owned!
Sounds about right! (:
AWW
Capybara and cat are the best of friends 
Does anyone know the names of the capybara and cat? 
The capybara’s name is Garibaldi Caplin Rous (or Gari) and the cat’s name is Flopsy. Gari is an amazing little (big) guy and tomorrow is his birthday!!
