I want to make sure I'm not on the track for obesity with my GCC, I keep roudybush crumbles and change out maybe weekly mostly just topping off, with sensible seed mix in another dish changing that out every three days or so (he seems to really like those lil white seeds) so just dumping out the pumpkin seeds along with the yellow pellets he doesnt want lol. I know roudy bush states it should be used solely but I love seeing him enjoy the vareity. will giving him access to both cause any issues?
