I adopted Sidney from the local animal shelter. He was microchipped, so I had to wait several weeks while the shelter tried to find his owner. In the car on the way home, he started making strange slurping noises. I didn't know what it was, but I thought he might just be nervous about the new situation. A few days later, I was talking about my new pet during a staff meeting. A co-worker told me a friend of hers had his cat given away by the shelter. I thought it couldn't possibly be the same cat, even though he was also a microchipped, declawed, brown tabby. Then she told me he had a peculiar trait....he chewed on his tongue!
