A friend of mine contacted me for help with an injured stray a friend of hers saw around their house... I haven't seen the cat yet but she said the cat's leg was injured. I am worried because no one has seen the cat for a few days... I was going to try to catch the cat and get her seen by a vet but now I don't know where she is. I am trying to decide if I should try putting a cat trap in the person's backyard, (it's a 2-flat) but I have to be careful because I borrowed the trap from a local shelter and if it's stolen or something I will be the one responsible...
