【发明】猫捕捉活鼠，老虎吞食活人，虽然体型大小不同，但禀受的性情并无二致。老虎咆哮能生风，故用于治疗风痹引起的肿痛；猫叫声起老鼠逃窜，故主治由鼠类引发的寒热病症。因此，《肘后备急方》取猫肉煮羹以消除鼠瘰（淋巴结结核），无论是否溃破均可治愈。但猫肉助湿且易引发毒邪，患有湿毒的人应当忌服。猫的头部骨骼及脑、眼，用酥油炙烤后，也能治疗瘰疬和鼠瘰。猫的毛保留药性后外敷，可治疗瘰疬溃烂。猫尿可治疗水蛭（蜒蚰）进入耳道，滴入耳中即可使其退出，方法是擦猫鼻或用生葱刺其鼻孔以获取猫尿。猫粪可治疗痘疮内陷不起，取腊月干燥的粪便烧存性后使用。猫胞（胎盘）可治疗噎膈反胃，因其具有未散的纯阳之性，故取其意以开通阴邪凝结之症。方剂用法：取一个完整的猫胞，用酥油炙烤研为细末，加入少许脑子（冰片）、麝香、牛黄、郁金，用唾液调和服用。我曾以格物致知的理论推究物类特性，猫的形体属阳而功能属阴，其性情禀受阴贼之机巧与窃盗之态，对应地支中的寅位，所以它的眼睛夜间视物精明并能随时收缩瞳孔，善于跳跃且嗜好腥生食物，不吃熟食却能消化血肉生物，这一切都是风火之气在起作用，遇到雪水就会蠢动，这是因为雪的形体属阴而功能属阳，是物类相互感应的结果。像这样如果吃了长江中的鲚鱼骨头，其胎儿必定流产。按：《异物志》记载，鲚鱼是由鸟变化而来的，所以腹内还有两枚鸟肾，这与麻雀落入淮水变成蛤蜊没有区别。鲚鱼肉中的细骨如毛发般，粘附在肠壁上脱不下来从而导致伤胎，这也是物类感触相应的结果。
味甘，性温，无毒。
【发明】狸与猫同类但不同种。因为性味温散，所以其骨烧成灰后善于开通阴邪郁结之气，是治疗鼠瘰寒热的专用药物。《千金方》用狸肉治疗游风（风疹）。苏颂认为狸肉可治鼠瘰。华元化（华佗）取用狸头骨。《千金方》使用狸阴茎。总体都是取用攻毒破结的含义。李时珍说，狸骨和猫骨的药性相近，可以通用。

[Invention] The cat catches live mice, and the tiger devours live humans; although their sizes differ greatly, their inherent natures are not distinct. When the tiger roars, wind is generated, thus it is used to treat swelling and pain caused by wind-bi (Wind-Bi Syndrome). When the cat cries, mice scurry away, thus it primarily treats chills and fever associated with "rat" conditions. Therefore, in the *Emergency Prescriptions Kept up the Sleeve* (*Zhouhou Beiji Fang*), cat meat is made into a soup to dissipate rat-scrofula (tuberculous lymphadenitis), healing both ulcerated and non-ulcerated cases. However, it promotes dampness and triggers toxins, so those with damp-toxin conditions should avoid it. The skull, brain, and eyes of the cat, when roasted with lard (su), also treat scrofula and rat-scrofula. Cat hair, preserved in its original state and applied externally, treats ulcerated scrofula. Cat urine treats leeches (yan you) entering the ear; dripping it into the ear causes the leech to exit. This is obtained by rubbing the cat's nose with ginger or piercing its nostrils with raw green onion. Cat feces treat inverted or depressed smallpox lesions; dried feces from the twelfth lunar month are burned to retain their properties for use. The cat's womb (placenta) treats dysphagia, regurgitation, and reverse flow of food. Because its pure-yang nature has not yet dissipated, it is used to open knots formed by yin pathogens. The prescription uses one whole placenta, roasted with lard and ground into powder, mixed with small amounts of borneol (nao), musk (she), realgar-derived bezoar (niuhuang), and turmeric root (yujin), dissolved in saliva and taken orally. I once applied the theory of investigating things to understand animal classes: the cat's body is yang while its function is yin; its nature embodies yin treachery, cunning, and stealth, corresponding to the Earthly Branch Yin. Thus, its eyes see clearly at night and can contract and dilate at will; it is agile in jumping, fond of raw fishy food, does not eat cooked food but can digest raw flesh and blood—all due to the operation of wind and fire. It becomes active upon contact with snow water because snow's body is yin while its function is yang, demonstrating the resonance between different species. Similarly, if one consumes the bones of the Coilia nasus (Jing fish) from the Yangtze River, the fetus will inevitably be lost. Note: The *Record of Strange Things* (*Yiwu Zhi*) states that the Coilia is transformed from birds, hence there remain two bird kidneys inside its abdomen, similar to sparrows turning into clams after entering the Huai River. The fine bones in its meat are hair-like, adhering to the intestines and causing injury to the fetus, which is another example of resonance between species.

[Invention] The civet cat (li) is of the same family but a different species as the cat. Due to its warm and dispersing nature, its bone ash is excellent at opening qi stagnation caused by yin pathogens, making it a specific medicine for treating chills and fever associated with rat-scrofula. The *Essential Prescriptions Worth a Thousand Gold* (*Qianjin Fang*) uses civet meat to treat wandering wind (urticaria). Su Song claimed it treats rat-scrofula. Hua Yuanhua (Hua Tuo) used the head bone. The *Qianjin Fang* used the penis. All these applications share the meaning of attacking toxins and breaking accumulations. Li Shizhen stated that civet bone and cat bone have similar properties and can be used interchangeably.
