Our two cats Smokey and Isis needed a bath. It was something that they did not enjoy, but they did allow it, but not without some protest. Probably would not worked out as well with two feral cats. If I had just saw two feral cats outside and decided to help them by giving them a bath. Funny how that is Smokey and Isis allowed us because they knew and trusted us. Two feral cats would not know me or trust me and would definitely not have allowed me to give them a bath.
Our cats could not understand what needed to be done. Even if I could speak with my cats and explain I do not believe they would agree that a bath was a good thing. They would probably say their way of cleaning themselves (licking) is just fine. In the end they will just have to accept that what I say is best and they will do that because of their relationship with me.
Maybe that is how it is with somethings God feels I need in my life. I think I do not need that in my Life. In the end I just have to trust that HE who gave HIS son for me knows best and can be trusted to do me no harm.
