Yesterday I turned one of my pet lilac, but I don't seem to get the Achievement. Is there a special page I have to visit? I tried the pet profile, but it didn't work. Also somenone gave mit the hint to visit the abandon site, but that didn't work either. TIA!

Visiting the full pet page unlocked:

High Level! Level your pet.

Strong Pet! Have a strong pet.

Strong Defender! Have a defensive pet.

Lots of Health! Have lots of health points.

Speedy! Have a fast pet.

Coming back here finally got me:

Have a glacier pet! and Have a lilac pet!

Thank you very much . I want even aware I was missing the other six.
