I have two cats, brother and sister from the same litter. Bolt, the sister, has a serious problem with door dashing. My fiancé and I have had to chase her down the street three times the last week. They're indoor cats because we live next to a busy road (and I really don't want to take the chances on that), otherwise I'd have them indoor/outdoor because I think it's horrible just keeping them in the house. The brother never tries to leave but the sister is much more adventrous, I'm thinking about getting her a harness and taking her out for walks because I don't know what else to do. I want them to experience the outside but when I try with the brother, he won't have it. I'm tired of trying to run off after her though, on top of the fact she doesn't listen to either of us. Anything we could do?
