New here.
My robo was purchased when small, now with me 2 years d.
After first full year, he's "eggs" / "balls" grow big, seems like abnormal for it's small body. whenever he craw around the cage, the wheel, the toilet, his "eggs" was kind of pumping on those things (ouch for me). And when he sits, it's like sitting on his "eggs" too.
Besides that, everything was fine. He plays, eats, run like he used to be (when those "eggs" were still "invisible".
Is this normal?
Is there similar post before where i can look up for?
Thanks
