If you attempt to target it, you'll have it targeted for not even a second, but if you time it right with a kick or bash, you can get agro and lure it out of it's cage. it is about level 2 in it's strength, but it will agro any guards you near, so if you want to try to kill it, best bet is to do it on the spot. His feeder won't interfere (the quest giver). Also note - he has remarkable Hp and Dodge. At level 47, hitting average 110, with a moderately salow attack, and max 2hs skill, I landed maybe 1 out of 8 hits, and did not see much harm befall the lil lizard.
Well, thats all the info I can give ya. Good hunting.
