I agree that cats are a problem in many areas, especially to birds, reptiles, and small mammals. However, cats are not evil, they are merely obeying their own predatory instincts. The issue is with cat owners, and those people who dump their unwanted cats to fend for themselves. I have 2 cats who are indoors because I enjoy having birds in my yard. It's my responsibility to make sure the cats can't hunt the birds, so they stay indoors (which, BTW, is a lot healthier and safer for the cat anyway). They are separated from my herp room, and they have each other for company, so they're perfectly happy.
Your basic premise is sound, but it's unfair to blame them when it's people who should be responsible for their pets. Many, many cats are injured or die every year by people who abuse, neglect, or abandon them, just as is the case with many reptiles. It's important that we seek humane treatment for all animals, and put the blame where it rightfully belongs: with people.
