There are several items in the collections (pet, mounts, toys), that are showing up but are not available to players. Similar to Wrath Classic, these should be hidden if not obtainable. These are:
Mounts

Lil’ Deathwing - Cataclysm Collector’s Edition - ONLY HIDE THIS PET IF UNCOLLECTED, SOME PEOPLE MAY HAVE THE PET FROM OG
Edit: It has come to my attention that the Lil’ Deathwing pet is not being granted to those who have the Cataclysm Collector’s Edition. This may be a bug.
In addition, the following pets do not show up if you don’t own them, but are obtainable in Cataclysm
Scorchling - Originally obtainable from Ahune in TBC, it was removed from his loot table in WotLK. Now obtainable once more from the Molten Front.
Celestial Dragon - This pet was in WotLK’s database but not obtainable. Now obtained from the 150 pet achievement in Cataclysm.
Lastly, some unobtainable Heirlooms exist in Cataclysm’s database. Some of these do become available in later expansions, though.
The following Heirlooms were NEVER available to players:
- Ring - Antique Myrmidon’s Signet
- Ring - Burnished Dark Iron Ring
- Ring - Gleaming Seal of the Archmagus
- Ring - Ornate Band of Accuria
The following Heirlooms are not available to players, but become available in Mists of Pandaria:
- Legs - Burnished Legplates of Might
- Legs - Polished Legplates of Valor
- Legs - Mystical Kilt of Elements
- Legs - Preened Wildfeather Leggings
- Legs - Stained Shadowcraft Pants
- Legs - Tarnished Leggings of Destruction
- Legs - Tattered Dreadmist Leggings
If there are any errors or additons, feel free to add on, but I think this is everything.
Edit: While I don’t plan on checking on all of Transmog right now, there is an easy outlier right now. Under the “Shirts” tab, there are only 2 appearances currently. One of those appearances is granted by either an “Epic Purple Shirt” or a “Legendary Shadoweave Shirt.” However, neither of these are obtainable. “Legendary Shadoweave Shirt” was never made available to players, while the “Epic Purple Shirt” was a TCG reward.
