At the end of a long day, who wants to sift through a messy litter box? Certainly not me. Up until now, the litter-box has been a necessary evil, a small price to pay for our beloved companions. But not anymore. In fact, there's an underground alternative designed for those of us who are ready to kick the litter habit: toilet training your cat.

Sounds complicated, right? Not at all. Although far from mainstream, cat toilet training is gaining momentum and cat owners across the country are beginning to embrace the trend. But before you toss that box in the trash, there's a few ways to tell if your cat is ready to take the leap into a litter-free lifestyle. Think Fluffy has what it takes? Read on.

1. Your cat is already litter-box trained.

OK, I know what you're thinking: "Of course my cat knows how to use the litter-box" But the simple fact is, cats that already know how to use the litter-box can be reconditioned to use the toilet instead. That's because cat toilet training utilizes your cat's natural instincts to bury their waste to hide their scent from predators. During the training process your cat will learn to put its waste in water instead of in litter. Once your cat makes this transition toilet training becomes a breeze and- voila! Your cat is successfully potty trained!

2. Your cat is eager to please you.

Does your cat love making you happy? Whether she leaves the occasional "gift" on your doorstep or offers a warm nuzzle while you're reading, cats who are eager to please are the purr-fect candidates for toilet training. After she learns that using the toilet pleases you, she'll be happy to oblige!

3. You have trained your cat to do something in the past.

Does your cat come when you call them? Believe it or not, simple actions like responding to a voice command can help lay the groundwork for the toilet training process. After all, if your kitty already knows how to "follow the leader", toilet training will be a breeze.

4. Your cat is healthy.

This one might seem like a no-brainer, but healthy cats have a much easier time jumping up onto their new throne. Illnesses like arthritis or urinary tract infections can affect their ability to learn how to use the toilet, so sick kitties should stick to the box.

5. You know your cat.

Can you tell when your feline friend is having a rough day? If you're like many pet owners, you're probably very in tune with your cat's feelings. This unique bond works as a positive force during the toilet training process. How? Cats will use body language to tell you if they are comfortable with a particular training step. When you pick up on these signals, both of you can work together to achieve a relaxed training pace. You'll both feel satisfied when you work as a team!
