i dont see why not! if youre going to use that excuse tho i would make sure the cache shows the pet on your account after april 1st before you go posting anywhere or anything
like i bet most of the newly adopted UCs dont have a cache but
say youve had one for a while and it does? and someone looks? and it's been on your account since like early march and people begin to ask about it if you show it off?
excuse not so good anymore
EDIT: also yeah pc went nuuuuts
apparently there was a WN UC plush zaf and a VWN UC faerie ixi. i call bullshit on the last one b/c i only saw one person talk about it
