Command-line Giphy using iTerm2's imgcat (also requires curl and jq)

giphy.sh

#!/bin/sh

tag="$(echo "$*" | sed 's/ /+/')"
random_api_url="http://api.giphy.com/v1/gifs/random?api_key=dc6zaTOxFJmzC&tag=$tag"
gif_url="$(curl "$random_api_url" 2> /dev/null | jq '.data.image_url' -r)"
curl "$gif_url" 2> /dev/null | imgcat

For some reason I get imgcat: command not found but you can clearly see it's installed and working if I call it directly from the command line. I tried both bash and zsh. Any ideas? Thanks!
