Abandoned cat (Whitwell)

Several months ago our neighbors moved and left 6 adult cats behind.
I already have 5 indoor cats so I felt obligated taking up the responsibility to care for them.
But unfortunately it’s just sad to see them everyday and I’d love to find them homes please.
Out of the 6 cats you can now pet 5 of them and 2 are super friendly, I believe 2 are pregnant and last night on 1 ( the smaller dark female) I noticed a concerning wound on it’s belly/back leg area.
I haven’t check it again to get pictures but it definitely will get infected or worse if not properly taken care of, I have some medicine I can use for now.
She isn’t acting in pain but it looks bad.
Last month my owe cat was hospitalized for a week and passed unexpectedly so I am in to position to get this poor cat vet care.
I really wish I could.
I hate seeing them living like they have no true home, the new neighbors that moved in doesnt want the cats so they don’t feed them or anything.
