Short animation about a cat watching from the window and dies at the end

Hi,
I’m trying to find a short animation I once saw. I don’t remember much, but I think it was about a cat watching from the window, trying to exit/escape, people (maybe a little girl) passing by each day. At the end the cat dies (ran over by a car?) and its owner had like a lot of jars with ash of previous dead cats. Not very sure about details. Might’ve been part of a short animations festival like animafest but I’m not sure.
If anyone saw it or can provide some info to find it again, please, it was so funny and well made.
Thanks!
