Biology

Reproduction:

Puberty (the age where cats can reproduce) in the cat ranges from 4-12 months, which on average is 6-9 months. You will know. A cat in heat is very vocal, calling and calling for a male cat. She will roll and roll on the ground and constantly rub against furniture or your leg. She will assume a breeding posture with her head and front legs near the ground and the rump area held high. She will become very affectionate. You may notice her urinating frequently. She will be in heat and accept a male for 3 to 16 days. A female cat is also unusual in that she basically will keep coming back into heat every 14-21 days or so until she is bred or the amount of daylight decreases (October).

Pregnancy and litter:

Generally, a cat has 4 to 6 kittens in each litter. The average cat could have 3 litters a year. Cats generally have their kittens 58 to 65 days after they are bred.

Nervous system:

Cats are born blind and deaf, these senses usually develop in about 2 weeks. The nervous system fully develops as the kitten grows older, excepting any trauma or infection that can hinder this process. The central nervous system is responsible for the brain and spinal cord messages, the peripheral nervous system affects muscles and movement, and the autonomic nervous system controls the involuntary functions of the body.

Digestive system:

Since a cats diet in the wild consists mainly from the meat of other animals, the feline anatomy contains a digestive system that creates acids and enzymes appropriate for the breakdown of food and destruction of bacteria. A cat's teeth also play a role in digestion by tearing sharply at meats and other substances. Much like other species, the salivary glands, esophagus, stomach, intestines, liver and kidneys work together to aid the digestive process.
