We called a vet, who told us to call animal poison control, who told us to go to the vet. My husband is on his way!
My poor girl!!!!!! I am so upset at myself, that I didn't even notice when it dropped, or that a pill was missing until now. We picked up the pill case three hours ago, and she just started this a little while ago, so it could be that she ate the pill recently.
My 9yo son feels guilty for not "locking" his pill case, too (it has a little button that locks it, but it could easily pop if dropped).
I was just telling my husband yesterday that while I love my cats, I don't know if I'd ever feel attached to them the way other owners seem to be attached... and here I am in tears and sick to my stomach!!!
