I think people mourn pets harder and its only natural. Pets dont bad mouth you, feck you over and are always happy to see you. So when a pet dies there are no bad memories (even if your dog chewed your fav shoes – end of day its just a dog and nos no better)
People feel silly when they cry over loosing a pet where as i think its perfectly ok.
Feel better soon Mrs T. and give tuppance extra rubs from me xx.
