Category talk:Tool-using species

To be included
A list of animals that use tools for feeding, intended to be exhaustive as of 1971, includes some species not yet included here. --Nethgirb 02:28, 29 April 2007 (UTC)

Inclusion of 'Pig'?
This category includes a mention of 'Pig'. I am certainly no biological expert, but Wikipedia's own articles: 'Pig' (genus Sus) makes no mention of 'tool'; and 'Tool use by animals' makes no mention of 'Pig' (or 'Sus'). Also a brief web search turns up nothing for the subject, which may be expected to have made some impression with the media if discovered... It would be much appreciated if someone more knowledgeable would substantiate or otherwise.159.253.68.152 (talk) 03:48, 24 November 2012 (UTC)
 * I have just been working on a major re-write of Tool use in animals. I also found no mention of pigs.__DrChrissy (talk) 20:42, 23 August 2013 (UTC)
