A zinc deficiency can negatively impact your levels of testosterone. Studies have shown that zinc supplementation can help increase testosterone levels. Zinc supplements, oysters, beef, pork, crab and fortified cereals offer great sources of this mineral.
Do not breed unless you own healthy animals with excellent breed characteristics, and you are very committed to these kittens preferably for their lifetime. For each home you find for your kittens, there is a kitten at the shelter being euthanized. Age at breeding. A female cat should be allowed to attain her adult size before breeding. If bred early, she will put her energy into feeding the unborn/newborn kittens instead of finishing her growth. She will be 18-24 months old before she is ready for breeding. A male should be 18 months of age prior to being allowed to breed. This allows time to determine if he is healthy and suitable for breeding. Temperaments are passed to the offspring as are genetic diseases.
At 6 months of age, a female cat can already reproduce. (If you use the seven-to-one rule, a 6 month old cat would be equal to a 3 Â½ year old person, and 3 Â½ year old people cannot reproduce.). In my chart, I figured that humans can reproduce around age 15. At 1 year of age, cat bones fully stop growing. This occurs in people at approximately 24 years of age, give or take a few years. Using this information (and 23 years of veterinary experience), I tried to devise a more realistic cat-human age chart that ends the seven-to-one rule once and for all.
