My cat was terribly afraid of getting into the old hard surface pet carrier and would go stiff if he even saw it.  When the I-G02 Carrier arrived, I unzipped it and set it out for him to inspect.  He sniffed it, walked around it and then stepped inside on his own.  Travelling with my cat is now a pleasure and since he can see around him, he has lost his fear of a carrier.  I am so happy to have found this product for both of us.
