Linguistic evidence is also against the  pre-European introduction of cats with 
Aboriginal words like 'walikatja' for wild cat and 'pudikatja' for pussy cat.

Aboriginal people swiftly incorporated cats into their diet but, as I stated 
previously, there is no archaeological evidence of pre-European consumption of 
cats.
