Learning vimscript so I can have my cat in vim (Changed to neovim so I am now using lua)
Download the cats.lua file and add it to a folder under ~/.config/nvim/. I personally use ~/.config/nvim/lua/
In your init.vim add:
lua require('cats')
To have the cat spawn on neovim launch add the following line to your init.vim
let g:cat_on_start = 1
To have a different cat edit the ascii_art variable at the top of the function, try to make it a rectangle for best results.
