Please, help me remember the name of this manga! I think it is a one-shot.

It's about a girl who has a two-tailed cat as a pet, told from the cat's POV. The cat is either immortal or long-living. I remember that a lot of time passes, and in the end the cat meets that girl's granddaughter, and turns into a human for a short time...That's all I can recall)

Thank you in advance!)

I found it!) The second story from Shoujotachi no Kaidan
