Eyes open? That would make them 5 weeks or more. Should be little potbellies at this point but the weight sounds too low. Don't have a scale or I'd weigh my kits right now. Would suspect 5 weekers to be about double that weight but this is a pure guess. Weight varies extremely from litter to litter until they reach mush more adult ages. bill and diane killian zen and the art of ferrets mailto:[log in to unmask] mailto:[log in to unmask] http://www.zenferret.com/ [Posted in FML issue 1603]
