Dogs and me have a very cordial relationship since my childhood. They trust me and I trust them. With cats it has been on and off, some have been best of friends while some would want to send me to the moon. Right or wrong my conviction is that mostly when you treat an animal well, it will treat you well too.
I believe if evey institute had one or two institute pets, it would go a long way reducing exam stress in the students and help them bond better.
I would not mind supporting a pet, would you?
