wow what state are you in?? I am in Florida and my neuter was $100.oo inc. pre op exam and go home pain med....Check around. Is dad fixed? How old is sister..If he is real young may not be of age to breed....I assume dad is fixed or he could get mom and sister preg ....
Do you have a second cage? Are you talking about a couple of weeks or a couple of months???? I would think if it is only for a couple of weeks may be ok as Mom would still have daughter's company...but it needs to be done ASAP.....PM Rach, Jett or KO..they are from Australia and it is daytime there...or check the chat room and see who is there...Good luck
