Yeah, I guess so too. :P And not just because the cat took a dump in it. We know cats don’t just drop their poop anywhere. They do it mostly on dirt, which means your gutter might have accumulated quite a lot of it for the cat to choose to poop there.
My wife let her in the other night because it was cold and she peed on a throw pillow. She'll go anywhere, especially if it'll piss me off.
Well, Antonia is right! Aside from that, the mere fact that the cat may keep coming back there will pose a problem. Their sharp claws can scratch the surface of the gutter and the roof, which can prove damaging in the long run, if it keeps on returning. Another is the weight of the cat may wear on the gutter over time. Taking that first step and cleaning the gutter is definitely a good idea.
I should just get rid of the cat...
I have to agree with Antonia and Lilia since they explained quite well how would this cat could cause you a lot of troubles in the future. Gutters serve as a passage way to funnel the liquid and avoid dirt build-up, especially on the roof. Getting rid of the cat may be too harsh, so why not train it? Just an honest suggestion. :)) Joann Winton @ AJC Roofing
