Totally understandable! I did a lot of research before getting them, I just get anxious about these types of things because I’d hate for them to not feel comfortable here! The breeder picked them up so easily I was amazed haha!Its completely normal for rats to be nervous! Some will take a few hours, some can take weeks or even months.
Sit with them for 10-15 minutes a day, and talk to them.
You can also try the yogurt on spoon/finger method.
Can you post a picture of their cage please?
Here’s some pictures; I tried to make sure they had plenty of hides and toys to entertain themselves and feel comfortable! I actually just had some come in that I need to put in !
EDIT: Had to fix the cover for their ramp now that I noticed 😂 Oh! And I forgot to mention they're both 7 weeks old!
