I've always wondered why some people who say they love dogs seem to vehemently hate cats. There are so many misconceptions about cats perpetrated by people who know nothing about cats but yet have no trouble trying to profess their knowledge. I've had cats the majority of my life. They will use the litter box or go outside religiously. If they are not doing that, something is wrong, either health wise or the litter box is full of excrement. Cats don't like using a litter box that is full. About the same as humans not liking using a full porta potty. Cats are CLEAN. Their saliva also makes them smell better or no scent at all. Remember they are predators. If you encounter a bad smelling cat it has health problems or something else is wrong. Contrary to dog lover statements cats can and will retrieve if taught. Cats won't do it incessantly until you are sick of seeing them. I've had cats that loved to travel with me, cats that are affectionate and cats that aren't. I've always trained my cats. Most of the time I find that dog "lovers" who hate cats grew up on a farm where they never interacted with the cats, just hunted them. Or they are hunters who think that only wild cats eat nesting bird eggs, wild dogs "never" do that. Yeah right. Me I love both dogs and cats, but I dislike people who haven't trained their pets to behave. BTW, dogs are way worse than cats for misbehavior.
