My kitten was mistakenly step on?

I posted this two nights ago For one I would Like to thank all who responded with concerned thoughts I was scared for my poor snowball and unfurtunetly at the time I had no way of getting him to an emergency care facility because the place is 5 towns away from me and I don't own a car so that was my purpose for reaching out I wanted to see if there was anything that I could do to keep him comfortable until I could take him in the morning :-( NOW for all you stupid s first of all I didn't step on him!!! my 4 yr old son did by mistake so kuttos to you for making a 4 yr old want to cry even more I think it's bad enought that he thinks he killed snowball and to Katy you can suck my big toe I don't know who the hell you think you are but I was told that a stupid question is a question that is never asked You want snow ball come and get him !!! But for those who was really concerned about him and not hurling insults at me snowball is doing fine he went to the vets yesterday !!!
