A black and white tuxedo cat with green eyes looks at the camera white sitting on a window sill

And can’t forget Finn, the resident cat on National Cat Day, who is an excellent big brother to all the foster kittens.

A picture of a tiny grey tabby kitten sitting up in his hind legs, staring intently at a very large (comparatively) grey paw sticking up from underneath the door in front of him

A picture of the same tiny grey tabby kitten pouncing on the large grey paw in front of him and bopping it with his own tiny little grey paw

Foster update: mom STILL won't let me see the foster, but jokes on her, we are playing together anyway! #FosterBrother #Fosterkittens #BigBigBrotherEnergy #CatsofBluesky

A picture of Chico, a big white and black male cat, and Ralphie, a smaller grey and brown tabby cat, lounging in the same hanging cat bed. Ralphie has his eyes closed, while Chico has half his butt and his back leg resting on Ralphie's back. They both have have paw hanging out of the basket as if mirroring each other.

He's not heavy, he's my brofur. #FosterBrother #FosterCat #Boys #Catsky #CatsofBluesky
