Honestly pet stones are pretty easy to get these days, the universal one sells for 15 of the tokens from the Menagerie. Super easy to get that many a day, and close to enough for a second. I stoned many of the WoD wild pets, gave me the freedom to select the breed I wanted rather than taking what ever I got. Saved me tons of time to do other things, like leveling, factions and working on my garrison.
Your call, but so far I don't really see a reason to store the menagerie tokens so I am burning them up as I get them. Even still I have about 70 now that I currently don't have a specific plan for.
