There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
Agree that infection is the main cause of concern at this point. The holes look to be quite deep, infection can happen quickly I fear. Good thing that he can put weight on his leg, that's a good sign, most likely nothing is broken. So apart from infection risk I think it will heal.
Other real concern imo is starvation (and increasing weakness from not eating). Not urgent atm yet but it may be in a week or so. He does not have a (~ stationary) pride with females to fall back to. Only his brothers but they venture into other areas too much (following buffalo), I wouldn't count on them providing him with meals, at least not regularly, if K4 cannot keep up the pace. That is just hopeful thinking imo.
