We’ve been using Placekitten.com for some time, and really love it. This service has two major flaws however:
a) who are these cats? And do I really care?
b) dogs are also nice. It doesn’t have dogs.
The day before christmas, two years ago, we made a WordPress plugin which replaces the standard WordPress 404 page with a homeless dog.
This year we give you Place-a-pet. (Service has been taken offline since…)
We’re scraping pictures of dogs and cats from Hundstallet and Stockholms Katthem, to give you placeholder images in any size. Service is built on NGINX, only. Merry christmas to you and all dogs and cats. We like you alot.
