Found cat in London — Alert #2261

Good evening. I have been looking for my cat since Monday. A lady found him on the street and took him to the vet. The vet’s office contacted me to ask if I was still in the area, explaining that someone had brought in our cat; they checked his microchip and confirmed he belongs to us. I told them I was at home and asked if I should come to pick him up. However, the receptionist informed me that the lady who brought him in had taken him back and left him on the street where she had originally found him. He hasn’t come home since Monday, and I have no idea where she left him or where she took him. My little boy has been searching for him all day since Monday, calling out for him in the street, but he hasn’t appeared—usually, he would always come when my son called him. If anyone sees him near the park by Pinkwell School in Hayes, please let me know
