Have Cat Questions? Ask a Cat Vet Online.
I am sorry to hear you are worried about Sissie. My name is Rebecca. I am a veterinarian and will do my best to help.
Do you know what her brother died of?
Has she had any vaccinations?
Does she have any diarrhea?
Sorry for all the questions, but since I can't see and examine her, the more information I have the more I can help. Rebecca
