Purina cat cookies

Good day, I am wandering where I could find purina cat cookies. I have been looking everywhere for them and can't seem to get them. I emailed the address on the packet ********** but have not received a reply. Please I am desperate as my cats love these cookies. I just want to know are they discontinued or is a change of packaging taking place or what. Thank you so much for your time Kind Regards Raedene
