Help i can only adopt 1 pet

[sariyah.mcavoy]

i was adopting monthly pets but i could only get one so i adopted them and it didn't even show up in groups

That means you already got those monthly pets, it says you can only adopt one and after you click 'adopt' it tells you that you already got those monthly pets.
Check your groups and see if they're already there?

The Halloween event is up, not more monthly outcomes. So make sure you didn't misunderstand the news

They're all in your 2017 group. I checked.
