Soluble fiber traps water in the stool, thereby softening it, but it does
not swell as much as insoluble fiber. It is fermented into compounds that
can be helpful for colon health.
Insoluble fiber (e.g., cellulose from vegetables) also traps water but it
swells - adding bulk to the stool. However, this is not what we want for
cats. Cats are not designed to eat a high plant fiber diet that results in
a high volume (large diameter) stool.

Most people don't know that fruit trees need different fertilizer than other

encourage it to put out a tremendous flush of vegetative growth with very
few flowers and not much fruit.

事实上达尔文自传首先描述了自己早年对基督教的信仰——达尔文成长于基督教家庭，
接受过完整的基督教教育，甚至是以传教士身份登上了贝格尔号——如果达尔文早年的
思想没有一点基督教的印记，那倒是怪事了！然后话锋一转，立刻就说到“I for one
must be content to remain an Agnostic”。这种“将欲夺之，必先予之”的笔法是
