I'm so sorry you had this experience...was this on another site??? Unfortunately some people on the internet make it their daily goal to be mean and flaming to people. I'm very sorry you lost your dear pet

and yes it very normal even for a man to cry. Men have these kind of feelings too, but some men aren't comfortable with crying. It can be from the way they were raised or social conditioning.
Before my kids were born we had this beautiful black Persia cat who had cardio myopathy. We have to rush him to the emergency vet at 3:00 am and unfortunately he was suffering and nothing additional could be done, so we had to euthanize him. My husband held him and I couldn't even be in the room. My husband cried and we brought him home in his blanket. He cried while we buried him in the rose garden - we didn't like the idea of the vet mass burials.
So yes, it completely normal for men to cry and he shouldn't be ashamed in the least for expressing a true emotion. A pet is a pet -whether it's a cat, dog, hamster, snake etc - one isn't more deserving of tears. My pet is a member of my family as I'm sure your dear cat was and it's really hurts when we lose them. Whoever said those comments is a cruel insensitive person

looking to make you mad. Real men do cry and personally I admire a man who can express those emotions. My husband also cries when Extreme Makeover is on and he's a very strong man. Strength has nothing to do with crying - in fact a man who's confident with himself, is able to show his emotions without embarrassment. Once again I'm very sorry for your loss of this special member of your family
