Angel, my pet Guinea Pig is very talkative. He makes squeaking noises a lot. Usually, whenever I come out of the kitchen into the living room, he gets all excited, thinking I am bringing him some veggies to eat. So I have to run back into the kitchen to get him something. I talk to him and thank him for reminding me that it is his mealtime. I also talk to him as I am giving him his new veggies and taking the old ones out of his cage too. Rotting veggies don't smell very good, so it is important to take them out of his cage, as soon as he is finished with them. I keep all his veggies in the fridge, so they stay fresh, but of course, once they have been in his cage for awhile, they wilt.
He loves celery. He will eat the base of it even. He eats it leaves and the stalks too, of course. However, he needs a lot of vitamin C, so I give him kale about twice a day. It has the highest content of that.
