So Lowla is good about going outside to do her business but now that we're in a house and we spend the majority of our time upstairs we can't see her go sit by the back door so we went out and bought a call bell as per someone's suggestion here that I thought was brilliant instead of hanging some bells on the door knob. I can't get her to figure out how to tap the bell. When I go to the door she's staring at the knob and I try to distract her attention to the bell and get her to tap it but she just doesn't get it. So I've been taking her paw and tapping the bell with her paw but she's still staring at the door knob or the door in general, it's like she has no idea that HER paw rang the bell, but she definately understands the bell means the door is about to open. So how can I help her be more interested in the bell and figure out that she can hit it and it will call us to open the door? Or should I just put a different bell on the door knob (I really wanted to avoid this because we're house sitting and I didn't want something hanging there that might rub or scratch the paint on the door)?
