simey, I thought you might like to see a picture of
Tripod, who was part of a feral colony and took
two years to trap. When he was finally caught, people were concerned about him (he had lost a leg and was a bit beat up) so ended up taking him to a no-kill shelter I worked with. He was very scared and shy and took a ton of work, but patient people were rewarded with the sweetest and most grateful purrs. After two years of working with him, I ended up taking him home, where my foster cat Mamacat decided he was going to be her boyfriend. Tripod lived with me for eight years and died in 2012, and Mamacat died not too long after--I think she just missed him so much. She would definitely thank you for what you're doing (as do I) and what I'm sure will take a lot of patience as you get to all the toughest ones.
I forgot to tell you when we messaged earlier about my avatar, but Fuzzy was an indirect result of TNR. We were helping a restaurant owner in Memphis that had a feral colony, and our first night when we showed up to put the traps out, we noticed a new cat that no one had ever seen. Well, he wasn't exactly feral, as he literally jumped in our car when we opened the door. Once he came home with us, we didn't let him go.
