•Approach and Solution•
I essentially designed a simplified Twitter Feed for the Pets. All the user needed to do was enter when they planned to visit and when they planned to leave. Once they posted it, all their friends would be able to see the timeframe they intended to visit the park that day. The friends could also comment on their post to encourage visits at a different time.
All of the posts would reset at midnight so the only times posted were relevant for that day. This will ensure that the user doesn't accidentally use someone's time from a previous or future day when they look up when their friends will arrive at the park.
