My loving lap cat Kelso is almost 2 years old. He recently went missing for 2 weeks- I had to trap him and brought him inside. He is now acting wild and hiding behind our washer. He only comes out at night to eat . I am not able to check him to see if he was injured. I do not want to force him out. How long should I give him to feel safe again? Can anybody suggest how to get him to come to me so that I can check him for injuries? Should I withhold food to try to get him out to lure him with treats? I am very concerned- how long will he be so scared? Does he not remember me?
