I've had the boys for over a month now. Evee has been fully adjusted and living with them for awhile. Splat really looks up to her and I'm pretty sure he brags that Evee is his cool older girlfriend. Evee has a "just friends" look on her face though.
Splat is a funny dude. I imagine him as a cross country runner who is very obsessed with nutrition and fitness but still a really twiggy body. He runs on the wheel a lot. A lot. And he will take maybe 1 treat from me, but then refuses and hops on his wheel in regret of the snack he did consume.
Spork pretty much just sleeps. I swear there are days I never see him as he is naughty about burrowing under my cage liner no matter how hard I've tried to stop him. I poke him to try and rouse him out sometimes but I can just feel him grumble and try to ignore me. Spork does run on the wheel sometimes too, likely from Splat's guilt trips. Mainly Spork just wants to eat and sleep.
I feel like a horrible rat mom often. The boys are still awfully skittish of me. I can't bribe Splat with food and Spork I can't even get to wake up to come see me. They're really not coming out of their cage much at all as they're not brave enough to venture out and they don't want me to grab them. I'm not sure what to do differently. Penelope didn't take long at all to come out and explore- she was the naughtiest and bravest rat ever. And Evee followed her like a good side kick.
Splat wants to follow Evee but will only follow her on top of the cage.
