Robby snapped this photo  of a cat on the Red Line this evening. A cat in a stroller. A big-ass stroller, apparently. He tweeted:
What's wrong with this picture? Many things ...
Another commuter, AH, also took to Twitter, around 6:20 p.m. and was more specific :
Lady with a cat in full-sized/meant for children stroller preventing me and 8 other saps from going on T. #wtf #catbitch #mbta
FYI snippy woman on the Red Line: cats (& dogs) ARE allowed on #mbta as long as they're properly contained!!!
MzKeating chimed in :
[H]ave you ever tried to get a cat to walk on a leash?
Robby answered :
No, that sounds ridiculous. That was her rationale as well, along with cat does not like the escalator. ... Let's recap, cat, stroller, peak hours, capacity train. No, still not reasonable. Thing was gigantic.
