I'm new to this myself, but I do have mine set up in the living room, and, having not anticipated the problem, I chose a high traffic area. We also have two very large dogs and 4 cats. The cats are very interested, so I've designed his enclosure to sit high enough up that they have to stretch just to get their heads even with the bottom of the cage. The dogs pay him no mind unless he hisses (sounds like a cat I guess ), but even then their interest is short lived.
At first I could tell the animals and humans alike were making him nervous when we were too near (and considering his cage lies along a pathway often traveled, that was a lot). He wouldn't eat unless I sat 10 feet away, for example. I spray the cats with water whenever I see them loitering near the cage, but I'm sure that's only temporary help.
I can tell lately he's feeling more relaxed. He'll eat even when the dogs are right next to him, and also when I'm there next to him, and occasionally i can hold the cup for him, though he won't take a thing from my hand or tweezers, and more often than not will take a lunge at my hand. He seems to stay his regular green shade even when the cats are near, but he's still wary of them. If he's near the bottom he'll retreat to the top if the cats seem to be watching him. Because he's so high he sees all activity below so it seems I've shielded him from them a bit but not the other way around. He's always aware of them. I'm hoping for the best, and so far, it seems, so good. He seems healthy, in good color, and he's eating with gusto.
