Cats is a strong online sector, that's why I have cat.me.uk. However, the wording of your domain does not have a strong meaning, and that's going to devalue the domain a lot. I assume you regged it as a "cats for sale" site? I think the stumbling block with your domain is that it doesn't make that much sense and is not good English. I think hoping for a good sale may be optimistic, and you may have to put an affiliate site on it.
Hope that helps.
