I hope your Kitty pulls through, She might have eaten something bad, Not too long agoe I heard of some pet foods that were contaminated on the news, maybe she got a bad can of cat chow and it made her sick, I would ask the store where you buy your cat chow from, if they had recently had to remove any contaminated pet foods from thier shelves.

if you narrow it down and find out that indeed a product was contaminated you may have a law suit, if you can prove you purchased it, you can do this by getting product purchase staments from your credit card company or who controls your visa on your debit card.

each time they scan an item it has a scan bar code that rings the item up, if the item has a bar code from a contaminated batch of cat food, you may be able to track it down in your pantry by just asking the store the bar code numbers of any contaminated cat food brands you use.

when they pull a product they sometimes do it by batch or by product name that would be any bar coded item of that brand if they had to pull them all off the shelf rather then track down a bad batch.

My best advice is to switch cat food brands for awhile and dispose of any cat foods you have recently purchased just in case they are contaminated but first take a sample to you're vet to test for food poisioning bacteria befoe you dispose of them.
