The Book of Household Management by Mrs. Beeton

although originally a native of Brazil, propagates freely in England and other European countries. Were it not that they suffer cruelly from cats, and numerous other enemies, and that it is the habit of the males to devour their own offspring, their numbers would soon become overwhelming. Rats, however, it is said, carefully avoid them; and for this reason they are frequently bred by rabbit-fanciers, by way of protection for their young stock against those troublesome vermin. The lower tier of a rabbit-hutch is esteemed excellent quarters by the guinea-pig: here, as he runs loose, he will devour the waste food of his more admired companion. Home naturalists assert that the guinea-pig will breed at two months old, the litter varying from four to twelve at a time. It is varied in colour,--white, fawn, and black, and a mixture of the three colours, forming a tortoiseshell, which is the more generally admired hue. Occasionally, the white ones have red eyes, like those of the ferret and the white rabbit. Their flesh, although eatable, is decidedly unfit for food; they have been tasted, however, we presume by some enthusiast eager to advance the cause of science, or by some eccentric epicure in search of a new pleasure for his palate. Unless it has been that they deter rats from intruding within the rabbit-hutch, they are as useless as they are harmless. The usual ornament of an animal's hind quarters is denied them; and were it not for this fact, and also for their difference in colour, the Shaksperean locution, "a rat without a tail," would designate them very properly.
