While I'm completely disinterested in joining in the war on pedigree or not rats.
Can I please just say, leave your poor animal alone with her offspring! She does not need your help which should be made obvious by the fact that your chosen "perfect" nesting areas prooved completely unsuitable for her, she is an animal she knows what she is doing and you are interfering an awful lot. You're pretty lucky she didnt go bananas with you sticking a camera in there within hours of her stressful ordeal of birthing them all.
Please just have some respect for your pet's privacy and leave her to it for a while.
