Oh no! I can certainly relate to what you are going through and I will most definitely be sending out good thoughts and prayers for Tigger! And like Barbara says, you can't beat yourself up for missing something. We all know how good cats are at hiding their illnesses from us - why do that do that?

{{{hugs}}} to you and Tigger and hoping she is ok when you get home.

And if she's still not eating - start the shoving it down her throat now! The longer she doesn't eat the worse off she's going to be all around. Ask for the vet for some Hills A/D which is supposed to get them eating again - get the baby food, Tubby fell for the beef & beef gravy flavor. Get a syringe (without the needle) and squirt water down her throat if she won't drink. This all sounds rather drastic, but not eating and drinking will only make matters worse.
