Thanks for asking.:) Pearl's doing great but I haven't actually seen her poop in the box for quite a while now. Sky's poops are still a little on the mushy side and sometimes have a little blood in them.:( I hope that in time they'll improve. My vet said to just wait and see what happens since he didn't do well on the Fortiflora. Sky eats well and acts normally so I'm not too worried about him. Thanks again everyone.:)
