So basically i got this cat on thursday, along with his brother, his name is Sunny and the brother is Ray, they both seemed to like the place and really enjoyed being around the house for the first four days. But then yesterday, Sunny started running from window to window clamouring to get outside, i was foolish enough to forget to put the details of my house on his collar and my dad let him out yesterday at around 8/9 pm. It has been a day and i have gone out looking for him with treats and whistling (which always seems to coax him out of hiding spots) but with no luck. The previous owner who was a lovely woman guided me through the five days i was with him, and has been trying so hard to help me find him by phone (i live in Greenwich she lives in Leeds) i have been out day and night with no luck. (I will put a picture of sunny and ray together, he is the skinny cat at the bottom) Ray is in great distress but it seems that he knows that Sunny is around. He meows every so often at the window and always looks out for his brother. What should i do!??? He is spayed and Microchipped. He also has these stress problems which are medicated for. Any ideas!? Please i hate seeing Ray in such distress... But Sunny seems real smart and i am hoping to God that he remembers his new home and will come back! Please help me!!
