Decoration Suggestion -

Something the animals could use, especially if the animals could interact with it.

Back scratcher. Enrichment such as a giant rubber ball. Hats.

(Enrichment or scratcher should only be one square each, 2 at most. Hats wouldn't need to take up space but could be on the animals either optionally or seasonally. Maybe a hat rack taking up one space enables hats, or, just an optional setting.)

Are there any little (e.g. 2 person or park) benches? (Or rocking benches or chairs, such as depicted in the current sticker pack.) That makes land look homey. Maybe in different styles and/or seasonal or holiday 'skins' options (for any furniture, decorative flower pots or potted small trees; etc.) One or two squares should be enough for any furniture, or potted plants, too. Small things.
