Hmm. So far that mostly gets me references to the fact that they'll fight over territory, but only one reference to what I want to know, and that reference is a guess based on casual observation of one pet. *sigh* 'Twas a word I hadn't thought of searching on before though.
I think territory is the word you need though, hope your searches prove more fruitful, sometimes a combination of words works better though I'm too sleepy to proffer any suggestions of same right now..
