Hi! I'm a new chinchilla owner of two young males. I've had them on Timothy Hay with Mint since I got them a few weeks ago. But, my mom came home with Timothy Hay with Carrot this time since they were about out. And I was wondering since it is still the same brand just with carrot rather than mint, can I switch them right over to it or do I have to introduce it slowly? Any help is appreciated! Thanks so much
