Having worked as an experimental lab cat for some time, i am quite qualified to answer this kind of question. i have rubbed ankles with many scientists and professors.
nah. trees don't have a central nervous system so they don't have anywhere to interpret their interactions with the environment. therefore they cannot feel pain as such, although there is often chemical response to the environment, such as in an aphid attack/drought etc.
what is more, feeling a sensation and interpreting it as pain are different things intirely.
For example when i go to the vet and the vet clips my claws it does not hurt, but i react to it in exactly the same way as when a clumsy research student (probably drunk) inadvertently steps on my tail. that is, i try to get away from the source of discomfort.
A person watching, probably interprets my reactions by your human interpretations of my behaviour.
oh, and thank you for stroking me. it was a most pleasurable sensation.
