Dilemma...what would you do?

Ok, I have a sort of problem...

I feed Serengeti..which right now, isn't available and won't be until the end of February or beginning of March ( I emailed Timberwolf). We are leaving on vacation shortly and I need cat food before we leave for our catsitter. Since I cannot get the Serengeti, and I don't have enough time to transition them to a new food, I'm at a loss as to what to do. I do feed part Wellness canned, but last time I tried to feed all canned, it was a MESS.

ANy suggestions or help as to how to switch fairly quick would be appreciated.

TIA!

ETA: I'm currently looking to see if anyone has any Serngeti in stock.

Do you have any left that you could blend with a new food? Would ordering online be an option?

I would just feed all canned and apologize in advance to the petsitter about it being messy.
