Brihat Samhita
मार्जारा भृशं अवनिं नखैर्लिखन्तो लोहानां मलनिचयः सविस्रगन्धः । रथ्यायां शिशुरचिताश् च सेतुबन्धाः सम्प्राप्तं जलं अचिरात्निवेदयन्ति ॥ २८-०५ ॥
If the cat should be found to scratch the ground with its claws, if metallic dross should be found to be of bad smell or if children should erect banks and bridges in the street with earth out of play, there will be immediate rain.
