Your creativity is no longer a kitten. It used to run after anything that caught its attention, leave tangles of yarn strewn across the sofa, stalk and leap upon and bite your toes in the middle of the night, and generally make an adorable mess of itself in the middle of everything.
Now it's an adult cat. It is more discriminating in its pursuits, though its logic in selecting them is perhaps inscrutable. Sometimes you won't see it at all for hours at a time, day after day, and then discover that it has been savoring the small nook behind the drainpipe under the sink. Sometimes it will keep watch from atop the refrigerator for anything worthy of its notice and decline to be coaxed into lesser pursuits. Sometimes it will unexpectedly revert to its kitteny love for being in plastic bags.
Point is, it's still alive and it's still around. Keep its dish full (with good cat food, which includes an amino acid not found in dog food), keep its water fresh, keep changing the litter box.
