This creation provides a pigeon cage with adjustable grid gates, which includes: a cage body that forms a habitation space inside, and an entrance and exit are opened on the outer side of the cage body, the entrance and exit communicate with the habitation space； and a gate, It is pivoted to the cage and corresponds to the entrance and exit. The gate has a plurality of grid elements, and each grid element is pivotally arranged on the outer side of the cage at equal intervals. Each grid element has a telescopic structure, and each telescopic structure closes each grid element. The length and an opening length are varied. Each telescopic structure is adjusted to a closed length to close the entrance and exit, and each telescopic structure is adjusted to an open length to open a part of the entrance and exit； thereby, the effect of adjusting the size of the entrance and exit is achieved.本創作提供一種具可調整性柵門之鴿籠，其包含：一籠體，其內部形成一棲息空間，並於籠體之外側面開設有一出入口，出入口與棲息空間連通；以及一柵門，其樞設於籠體且對應於出入口，柵門具有複數柵元件，各柵元件等間隔樞設於籠體之外側面，各柵元件具有一伸縮結構，各伸縮結構令各柵元件於一關閉長度及一開啟長度間變化，各伸縮結構調整至關閉長度以封閉出入口，各伸縮結構調整至開啟長度以開啟部分出入口；藉此，達到調整出入口尺寸之效果。
