My Sallie Mae had a litter on Easter and there were 5 kittens. Two what I call Calico they were black with brown and white spots. Someone called them a tortie. I had two classic Grey tabby and an orange one. I went to work last night all 5 were fine. I was running late to work this morning and when I came home from he meeting I checked and Sallie was meowing like crazy and I saw both were gone. I removed them, but I have no idea what happened. My husband was here and he said he checked on them before he went to bed last night. Does anyone know why after almost 2 weeks they would have died? I called the vet no answer yet. There was blood on the bedding and I changed the bedding.
