I was in Walmart this week buying litter for my critters and noticed that Walmart had a new variety of scoopable litter in its Special Kitty store brand, and it caused me some distress. It was in a cheerful orange box, and splashed all over the box were the words "Citrus Scented." Cats HATE citrus. In fact, they hate it so much that it's recommended you scatter lemon or orange peels in places you don't want your cat to go, like in the mulch of your flower beds, for example. As an added bonus, slugs are also attracted to the peels overnight, so in the morning you can gather the peels and slugs up and dispose of them and then scatter more peels.
But I digress.
I see much disaster ahead when well-meaning humans unknowingly bring this stuff home and put it someplace where their furballs are supposed to go the bathroom. Cats have no way of saying, hey, I'm totally repelled by what you've just put in there, why did you do that? So they're going to be confused and distressed and are going to want to do their business someplace that doesn't repel them. So if your cat has suddenly started going outside the litterbox in places that distress *you,* like the living room carpet or your bedspread or your slippers and you've recently changed their litter to this new scent, you may want to run out and bring home some of your old litter, as well as a new litterbox. The old box can hold the offending scent in the plastic, especially if it's been in use for awhile, and in that case even changing out the offending litter won't help.
Litterbox issues, by the way, are one of the top reasons people give their cats up, because so few people understand the complicated relationship between a cat and its box. First you have to understand how sensitive to smell a cat is and how sensitive their paws are. A cat has a sense of smell 14 times better than a human's, and it can feel the vibrations from a mouse in the grass at 100 yards away. If their box isn't cleaned out at least once, preferably twice, a day of solid and liquid waste, they're going to find it offensive to their noses and touch and will start looking for someplace else to go. If their litter brand is suddenly changed, from, say, clay scoopable litter to those pine pellets or a wheat/corn-based one, they may find it upsetting and start looking for someplace else to go. This doesn't mean you can't ever change the kind of litter they use. It just means you have to do it gradually, by slowly adding small amounts of the new litter to the old until the new has replaced the old. Sometimes the process can take as much as a month, but it can be done.
And if a cat is having urinary problems, it will often associate the litterbox with the pain and start going outside the box. Cats who get urinary infections or crystals will often go to the box over and over and over in a short amount of time due to spasms in their urinary tract, and then they'll abandon the box to squat someplace in the house, leaving a tiny puddle which could be bloody. If you see this behavior in your cat, get him or her to a vet ASAP. Urinary problems, especially crystals, can be fatal for felines.
