not really a question more an observation; In the vet hospital I work, there are stables for horses and there is a secluded area for illegal fauna traffic that was confiscated; One day a truck pass nearby to go to the secluded area, turn out the truck was carrying a Jaguar. All the horses immediately went nervous and began to neigh really loudly.I think is incredible how they still react to predators even if they have been years apart!
It’s an instinctive thing, really. I wish I knew the details of it, but animals react very strongly to the smell of animals they consider a threat.
There was a day a while ago when I had been hanging out with an animal education company, and the last thing I had handled before leaving was a juvenile crocodile. I stopped at a gas station and this super friendly german shepherd came running over to say hi. The moment he sniffed my hands, he backed up about ten feet and started alert barking frantically. I have no idea if that dog had ever encountered a crocodile (unlikely) but he still knew something about that smell was fundamentally a big nope.
