this is her 3rd liter... she pulled furr for both past liters and had the babies around the 28th and 30th day. Today is the 30th day and she’s hasn’t even nested! Does that mean the kits died inside her so she’s knows not to make a nest? I don’t know what’s going on. Any tips would be helpful! Also I know she is defiantly pregnant . Her belly is very big and she has been digging in her cage ... she is also way more moody! Thank you in advance!!!
