وَإِنْ مَاتَتْ فِيهَا حَمَامَةٌ أَوْ دَجَاجَةٌ أَوْ سِنَّوْرٌ: نُزِحَ مِنْهَا مَا بَيْنَ أَرْبَعِينَ دَلْوًا إِلَى خَمْسِينَ
Translation: If a pigeon, chicken or cat dies in it, draw between 40 and 50 buckets of water.
These are medium-sized animals compared with a mouse or sparrow, so a larger volume is assigned. The bracket presumes the body has not swollen or decomposed.
