Well there are differnet forms/causes of Anemia. We are pretty much open to lots of possiblities right now.

It will be about a week before she gets results back from thet vet, and one of her older healthy cats was sent in for lots of random blood testings.

Possibly FIA, FIV, pesticides.

Her cats are not outdoors, they go on an outdoor enclosure, but it's really just a screened porch.
Her mother whom lives next door, uses this power based pesticied. We are trying to find out the name of that product.

Both cats died within 3 days of eachother, and she has about 10 other cats at home right now.
