Cat food recipe

This is the cat food recipe I was looking for the other day but couldn't find.  It's from the Choice magazine website and was developed by the professor of Veterinary Science at Sydney University, Professor Fraser:

Adult Cat
250 g boiled potato
600 g lean meat (lightly stewed)
100 g cooked human-grade sheep or beef liver*
20 g corn oil
25 g bone meal**
5 g table salt
Mix all the ingredients together and feed it to your pet once a day.

*A vitamin supplement can be used instead of the liver
**Bone meal can be found in certain healthfood stores and is an excellent source of calcium. 

Amount to feed each day according to body weight:

Cat weight	Food
2 kg	100 g
2.5 kg	120 g
3 kg	140 g
4 kg	190 g
4.5 kg	210 g
5 kg	240 g
