The present invention relates to a manufacturing method of paper cat litter, which utilizes the recycled paper as material and makes the pulp raw material into small particles of paper cat litter. Then, the surfaces of paper cat litter particles are cold-coated with a coagulant coating to enhance the absorption and coagulation effects. The natural materials, such as brewed tea leaves, coffee grounds or pine, are added to create an environment suitable for cat to stay. When the urine urinated by the cat is contacted with the paper cat litter particles, the coagulant coating on the surfaces may rapidly absorb the urine and the paper cat litter particles may be coagulated into blocks while reaching a certain amount. In addition to easy cleaning, the used paper cat litter may be flushed into toilet for melting or poured into incinerator for burning, which may meet consideration to environmental protection concern.本發明係有關一種紙貓砂製造方法,其係以回收廢紙為素材,將紙漿原料製成小顆粒之紙貓砂,再以冷鍍方式於紙貓砂顆粒表面鍍上一凝結劑鍍層以增加吸收及凝結效果,同時加入如茶葉渣、咖啡渣或松木等天然材料,打造適於貓隻棲息之環境,使貓隻排洩尿液接觸到該紙貓砂顆粒時,其表面之凝結劑鍍層可迅速吸收尿液,至一定量體時,該紙貓砂顆粒間可彼此凝結形成塊狀,除了易於清理外,使用後之紙貓砂也可直接沖入馬桶溶解或倒入焚化爐燃燒,兼顧環保訴求者。(1)‧‧‧紙貓砂顆粒(2)‧‧‧凝結劑鍍層(3)‧‧‧紙質層(4)‧‧‧貓砂盆
