Rather than to offer opinions on what animals can and cannot feel, I think it's of interest to note that there is a body of research on this topic, including a 183 page report:
“Aspects of the biology and welfare of animals used for experimental and other scientific purposes” EFSA Journal (2005) 292, 1-46
Of course, these guidelines don't necessarily apply to livestock. There are other regulations regarding those animals.
