Trust your own experience.
Pocket Pets is a very controversial topic. Some folks have great experiences with them and some do not. Some have opinions about PP without having any personal experience with them at all.
I don't personally have any experience with them, but I'm not one to bash them either. There are things I like about them and things I don't like about them.
One thing you will find is that no matter where you ask this whether its on this forum or another group or forum you are going to get mixed opinions. Some are going to be very heated and nasty some will treat you like a victim some will understand and be more open.
There is one group and only one group that I know of in the glider community ( not ran by PP ) that is completely Pocket Pet neutral. They neither promote nor bash Pocket pets, nor do they treat the PP owners as victims. It is a safe place to ask questions without getting mocked or bashed and get other PP owner experiences and opinions.

PP food "glider gravy" is actually repackaged critter love hpw a very well known and widely used diet.
I don't shop at PP, so I can't really tell you about their products. What I can say is PP is a very large company, and they have a lot of products to make money. PP has a pretty long history that many people don't know about, I didn't either but once I was told about the history it put a lot of things into a different perspective for me.
Be careful adopting other peoples beliefs as your own simply because you read it somewhere online. Educate yourself then come up with your own belief and opinion about it. There are many parrots in this community with many opinions, and that is all they are opinions....... most often if you ask those people for proof they don't have any.
