Gone are the days of egg custard slurries and a long impossible ingredient list. Echidna are held in most Australian zoos and Wombaroo was approached to make an Echidna food for adult animals. However, this food has been great for the wild Echidna that I have had in care this year. It is incredibly easy to make up - you just need the scoop and a measuring jug to measure the water. I have found that Echidna are happy to eat it. It creates a brown formed poo at the other end, which is easy to clean up.
