Best Answer: yes carbon dioxide is a pure substance, provided there is nothing else in it. as soon as you add some oxygen (O2) or methane (CH4) etc it is not pure. the actual molecule is CO2, one carbon and 2 oxygen atoms everytime which makes it pure. it is the same as saying pure salt. salt has sodium and chlorine in it but is still a pure substance provided nothing else is in it.
Yes, mother cats do mate with their offspring. I had cat which had become so old that my family members used to call her grandmother cat. I had once seen her mating with her offspring and THEIR offspring at different times!
Before breeding your cat, learn what is involved in mating, reproducing and delivering healthy kittens. Sometimes, breeding isn't a good idea. Puberty in a male cat, called a tom cat, sets in at 6 to 8 months of age when he is able to fertilize a female cat. The male's reproductive life can last 14 years or more.
