I know we have a lot of cat owners here, so I figured somebody might be able to help us with this problem. My cat (Cassie, about 2.5 years old) loves to be outside. She'll play, climb, chase little bugs, etc. She can spend all day outside if the weather is nice. But she's also a nice house cat, friendly, clean, etc. The problem we're having is that she likes to defecate in the neighbor's yard when she's outside. She's been doing this for a couple months now, but we just found out about it yesterday. We had no idea because we still see her using her litter box (by the way, she's been litter box trained since we've had her, and had no problems with that ever). Yesterday the neighbors finally decided to tell us. We have the same problem with other neighbor cats doing it in our yard, so we totally sympathize and were very apologetic. But because other cats are doing it we asked them if they were sure it was our cat. They said they're very positive because they saw her doing it. Is there any way to prevent this from happening again. The only solution we've come up with so far is to limit the amount of time she spends outside. But she stands by the door meowing to get out and won't let up. The weather hasn't been very nice lately, but she doesn't care. She still wants out. In fact it seems to be getting worse. Sometimes she'll come wake us up early in the morning to let her out. She's never done that before. Sometimes her persistance is a little suspicious...like she has to go to relieve herself and wants to go outside to do it instead of using her litter box (which she has easy access to without our assistance). I'm sick of hearing her whining to get out, but I also don't want her using the neighbor's dirt. They've tried the sprays and other deterrants with no success. Is she happier doing her thing outside or is she just doing it because other cats are out there doing it? Is there any way to stop this? Any advice? Thanks in advance.
