My son and I just today were discussing cats' fascinations with long, narrow objects. What in nature, I wondered, would be long and thin and attractive to a cat for any reason? His only answer was snakes, but I don't think that's it since so many would be harmful. At the time our cat was playing with a butter knife, having the time of his life. They all steal our pens and pencils if we leave them around. I have to hide my syringes or they disappear under the couch. In fact, I had one cat who would stick his fluffy head in my purse and fish for a syringe! He would be so cute, sticking that woolly head in and pulling out treasure!
