Every Sunday, a little old lady began placing $1,000 in the collection plate. This went on for weeks and weeks, until the priest, overcome by curiosity, approached her.
   "Madam," he politely said to her, "I couldn't help but notice that you have been putting $1,000 a week in the collection plate."

   "Why yes," she replied, "Every week, my son sends me money, and what I don't need, I give to the church."

   The priest replied, "That is a wonderful thing to do, ma'am. But are you sure you can afford it? How much does he send you?"

   The old lady replied, "Oh, it's usually about $20,000 a week."

   The priest was amazed! "How nice that your son is so successful. Tell me, what does he do for a living?"

  "He is a veterinarian," she answered.

   "That is a very honorable profession," the priest said, inwardly somewhat perplexed at the size of the income.  He then asked, "And, where does your son practice?"

   The old lady proudly replied, "Well, he has one cat house in Las Vegas and another one in Reno."
