Drop the soaked Orijen. It is not needed and if not eaten quickly will start growing mould. Ground beef is fine if kitty is tolerating it for short term. I find my guys don't like beef much. A raw egg yolk, no white, mixed in with the food is ok. A couple
of clams won't hurt if kitty will eat them. A tiny amount of salmon oil won't hurt. Of course the weekend is coming quickly for you to get the proper food for this kitty.
Are you planning on taking kitty home with you?
