hey guys. my stimmy is really close to outgrowing her first home I recon. I'm gonna give her another tub that's a bit bigger but was thinking I might attach her old one to the new one cause I know she feels happy and safe in it literally never struck at my hand when I go to pick her up. my question is do you think I should do a double home for him that can provide a bit more of a heat gradient / more places to be or just give her the bigger tub?
