Hi, my cat is a Siamese breed and he is 2years old, he is a indoor cat since he was a kitten and has always had access to the balcony and is happy and normal when he is out on the balcony.....but we bought a harness and lead and took him for a few walks outside around the yard but if we go near him or touch him he growls and his fur gets puffed up and he just flips a switch and is totally feral and it is a mission to get him back inside but when inside he is normal and fine again...we want him to enjoy his time outside but he is just too crazy when he is out.....does anybody know why he acts like this?...
