Another night has passed. Sebastian (nor Siren) have yet to poop.
I spoke to my vet today, and he said I don't have to bring either cat in (yay!) but I do need Sebastian's stool sample as soon as possible. The vet just needs to see what kind of worms they are, since he came from outside and all, and I'll get medicine for both kitties.
I cannot believe that neither has taken a shit yet though. Not that I need Siren's poop, but it's still kind of mind-boggling that she hasn't gone to the bathroom either. Weird.
Also, can someone please explain to me why Siren is going around the apartment licking plastic bags?
