Hi there, It sounds like the cats in question are the free Firestorm cats. The Firestorm cats do not update, so they are unable to appear on the new 2.0+ HUDs. They will appear on the old Legacy HUD though.
If you have any other questions or issues, feel free to reach out to me, one of our CSRs or file a support ticket and we will be more than happy to assist you further. Thanks
Older Perma Cats dont show on HUD
