Oh, poor Ilio! That scar is huge! My mum's cat had an abcess once which burst on the way to the vet, so all they did was clean it and give us antibiotics. The affected area wasn't particularly big though. The vet said that the size of the wound which had caused the abcess was "consistent with a cat bite".

Did they have any idea about what cuased Ilio's abcess?
