猫砂怎么选？基于猫科行为学的选购逻辑与省钱买法

膨润土、豆腐砂、混合砂到底哪种更适合你家猫？我们用 3 篇猫科医学文献，把「猫砂偏好—如厕行为—泌尿/肾脏健康」这条链路讲清楚，并给出可执行的选购清单。
一、猫砂不是随便买的：它直接决定猫愿不愿意上厕所
猫科医学里有一个共识：大量「乱尿」案例的第一处理步骤不是训斥，而是检查猫砂盆本身[1]。临床综述把猫砂盆管理（盆的数量、位置、砂的深度、清理频率、砂的材质）列为处理随地排泄问题的第一步，因为猫对垫料（substrate）有明显个体偏好，突然换砂常常导致拒用[1]。
结论很直接：换砂要渐进，7~10 天按比例混合过渡，不要一次全换。
二、泌尿/肾脏视角：湿度瞄向"多喝水"
在讨论排尿行为之前，兽医教材级综述强调：猫出现排尿异常时，必须先排查下泌尿道疾病（结石、栓塞、膀胱炎），再谈行为问题，尤其是老年猫[2]。这也是为什么"只看盆里的砂团变化"比"看墙角有没有尿"更有效。
饮水量是另一条主线：一项对健康家猫饮水行为的对照观察发现，吃 100% 干粮的猫自主饮水增加量不足以弥补食物含水量差，湿粮显著抬高总摄水量[3]。因此搭配主食罐/湿粮，是猫尿路和肾脏的日常保护手段之一。

Feline inappropriate elimination is the number one behavioral reason for relinquishment of cats to shelters and has historically been the most commonly reported feline problem addressed by behavior professionals. Veterinarians are hence challenged to uncover the underlying motivation for this behavior so that an accurate diagnosis can be made and an effective treatment plan implemented. Before a behavioral diagnosis can be made, underlying medical disease must be addressed, making a comprehensive physical evaluation imperative. After all medical issues have been addressed, a behavior diagnoses list is made based on detailed historical information obtained from the cat owner. A distinction is first established between marking and inappropriate toileting, according to elimination postures described by the owner and the social relevance of the sites of inappropriate eliminations. Next, inadequacies of the litter box management are identified and subsequent aversions and preferences, including litter box aversion, substrate aversion, location aversion, substrate preference, and location preference, can be diagnosed. The practitioner should be cognizant of the fact that anxiety from the environment and social conflict may play a major role in both marking and inappropriate toileting behaviors. Once both the medical and behavioral diagnoses are established, a treatment plan catered to the individual cat, owner, and household environment can be formulated. This should include acceptable forms of marking when indicated, appropriate litter box management and hygiene, reduction of environmental stressors, including resolution of social conflict in multicat households, proper treatment and restricted access to soiled areas, pheromone application, and, when indicated, anxiolytic drug therapy.
