There's no need to waste time scratching your head trying to find a great gift for the cat lover in your life; after all, you already know the feline center of their infatuation. With this starting point in mind, all you really have to do is narrow down the options and figure out what to get.
First off would be the most obvious. Do they have a cat? If you're shopping for your own child, it might be time to give in and get them a pet (not the best thing to do for somebody else's child unless you have permission).If you're worried about taking care of a live animal and your child is really young, a soft and fluffy stuffed animal could possibly bring just as much joy and much less work (cozy stuffed animals are a good option for girlfriends as well).
Does your gift recipient-to-be like or even collect figurines? Check out catfancygifts.com. They offer classic figurines, crystal cats, whimsical cutesy cats, folk art collectibles and more. You could also search for cat-themed painted porcelain plates. You'll want to consider, however, which kind of collectible is best for the intended household. For example, are there small children in the house that are likely to break anything fragile? Is the current decor modern and clutter-free or is it homey and eclectic? A gift that would be out-of-place in their home probably won't make the shelf.
Is your cat lover also appreciative of fine art? A fantastic, one-of-a-kind gift would be to commission a local artist (or one you find online) to create a personal portrait of the cat in question. This will be especially touching if the person you're giving the gift to has recently lost a beloved cat and would love to have its memory kept fresh. Usually the artist will only need a photograph or two of the cat to work from, and enough time to complete the artwork of course. Just search for "pet potraits," followed by the city you live in, or look at Doggonit Art for a more lighthearted take on pet portraiture. If you're really on top of it and know that your cat lover prefers watercolors vs. oils, or pastels over colored pencils, add that term to your search or talk to an artist that excels in that medium; it will make your gift even more personal and impressive.
On the other hand, perhaps the cat lover in your life would appreciate gifts that go straight to kitty. In that case, your local pet store will have an overwhelming array of cat toys, for starters. What about a scratching post, climbing house, or other such structure? If you're hand with a needle and thread, consider making some homemade bedding for kitty or a miniature scarf for those cold days when fur just isn't enough. The pet store will also have aisles of pet clothing, with specific outfits for holidays if you'd like.
