How scary! That is so strange that Honeybun is bruised so badly. I think you must be right, he could have fallen from something to get a bruise like that. I could see how a cat fight would cause bleeding but not bruising.
Is there any way he could have found a way to get outside and back in without you knowing like through a basement or garage or something? Or maybe people in the house visiting roommates? Maybe someone tripped over him. My hubby fell over our cat Teenie the other day and they were both kind of shaken up.
In any case, I hope he will be on the mend with each day and feel better soon. Poor guy!!
