Ok so ive owned chinchillas before and i still have a 3 year old that is my baby girl, but when i saw these two up for adoption on craigslist and that the woman only wanted $70 for both of them i jumped. So i have them home now with their new cage all set up and i remember when ive introduced babies to adults before(through the cage bars no actual contact) the adults have always sniffede and tryed to nip and the babies always cried out. Neither of the girls do this when i hold them up for murry to inspect them =/ i dont understand it. The only sounds ive heared from either of them are when evie sits in the corner and squeaks after i give her a treat (about a third of a rasin) Also the girls seem very small for 8 weeks, granted i know chinchillas can become pregnent more then once at a time so i figure evie is a few weeks younger because of her size but in any case i was wondering if any of you can tell me what i should do about the girls not crying at murry when she inspects them through the cage and suggest if i should get the girls vitamins to help where their so small? Also i can post picture if need be.
