Not five minutes ago - you just said you were keeping your animals at your sisters - including the new one.
Hon, seriously - you're doing a dis-service to these animals. Your mom doesn't want them in her home, and your sister clearly doesn't want them in hers, otherwise she wouldn't let them starve to death.
So where are you keeping all these animals and how are you quarantining new animals?
I PROMISE you - there will still be ball pythons and RTB's available for you when you are an adult and in your own home.
Right now, you're having far too many tragedies with your current situation, and just based on what you've shared with us - you're acting impulsively by adding new animals.
That RTB recovered very quickly from the RI - what did they treat it with?
