So I was driving the HST on GWE with my cat sleeping beside me and I pressed the signal bell. Instantly she sat up and puffed herself up, before growling at the tv. I never knew HST signal bells can scare the heck out of cats!
I've also checked whether one of my Guinea Pigs reacts to the sounds of TSW2. I once saw that one of them reacted slightly anxiously when I released the brakes on the BR Class 40. Animals hate British trains
Our old cat (long gone now sadly) used to lay across my hand and wrist when I was trying to route build on the laptop. Basically he wanted attention or else no, no buildee!
