People often ask me when they should teach the Good News to their housecats. I have but one answer: "What are you waiting for?"
A pet is a beloved part of your family, and as a Christian, you should do everything you can to guarantee that this valued member of your family receives the glorious eternal reward for which Christ gave His very life. Think of the alternative: your cat mired in darkness for eternity because you put off a 10-minute conversation.
My own cats accepted Jesus into their hearts before they even opened their eyes. The light of salvation has brightened their lives, but perhaps the most noticeable change has been in me. I am filled with warmth knowing their eternal souls have been saved.
Kittens' hearts, at birth, are filled with what theologians call "original mischief." Mischief, if left to grow on its own, can sprout into evil. That's why you must fill their hearts with Jesus instead. If you wait, your cats might find seductive role models among the back-alley strays and rough felines from the wrong side of town. You could also end up with an unwanted pregnancy.
That's why it's so very, very important to tell your cats about the life, crucifixion, and resurrection of Jesus as early as possible. The Nicene Creed is a good place to start: Recite it to them when they are about 10 weeks old.
Remember: If you give a cat a fish, it eats for a day. If you teach a cat to fish, it eats for a lifetime. Perhaps that's not such a good proverb to use in this case, since fishing is actually instinctual in cats. But Jesus is not. Your kitties need to know early on that there is a fisher of men and cats alike who can save their souls.
A lot of people say, "Oh, but Whiskers doesn't even answer to his name yet." They raise a good point: Sometimes you have to teach your cat at its own level. If you give your cat a rubber Jesus to play with, it will sense that there's more to this toy. If you give it a scratching cross, it will contemplate Christ's love and ultimate sacrifice while it stretches and sharpens its claws. I myself have put an image of Jesus at the bottom of my cats' food bowls. That way, when they finish their food, the face of He who provided it is revealed unto them.
Teaching your cats the Gospel of Christ isn't just important for their eternal souls, it is also the only way to ensure that they know an eternity of damnation awaits them if they scratch your favorite chair. Before they cough up a hairball on the rug or leave a dead mouse on the doorstep, they'll know—without being scolded—that they had better watch it, as a Final Judgment awaits at the hands of the Lord.
Of course, once your cat has accepted the Lord in its heart, it's ready to be baptized. The righteous cat is one that is born again in the eyes of the Lord. People think that baptism is a rite that requires a fancy baptismal font and a preacher, but that's simply not true. Just fill your bathtub with water, say a little invocation over it, ask your cat if it rejects Satan and all his evil, and then dunk it. Make sure it is fully immersed, in accordance with Scripture.
So now, all you have to do is choose your cat's baptismal name. My cats' birth names were Meowser, Fluff, and Mr. Boots, but their baptismal names are Ezekiel, Caleb, and Mr. Paws.
Remember, a cat may have nine lives, but it only has one eternal soul. We all must one day appear before the Holy Seat Of Judgment, and although my Oliver and Lady Twinkles passed on long ago from this vale of tears, I take solace in the knowledge that, when the time comes for me to receive the ecstasies of Heaven, all of my housecats will be waiting to spend eternity on my lap.
And don't get your cats vaccinated, either. The Lord will provide protection from feline leukemia.
