I find Mr. Sinnot to be an educated, empathetic biologist who treats animals as humanely as possible, not the 'fear-mongering, biased, truth-denier' that this columnist portrays him to be. As the columnist admits, Sinnot is an 'experience wildlife biologist'. That's why I pay attention to his commentaries. He has a wealth of experience, and seeing him on the polar-opposite side of this columns' argument adds weight to his position, in my opinion. I love cats, and they are my preferred critter, bar none. Nothing like having a purring bundle of warm fur ensconced in your lap as you watch the news or read the paper. However, I have direct experience with feral cats and they are quite a nasty change of direction on your normal housecat. They have a direct, proven deleterious effect on small mammal and bird populations. If Ms. Robinson wishes to take all of Anchorage's feral cats to HER place, please do. But don't bring TNR -here-. Far more humane to put these poor critters down.
