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!
It is best for your own cat's health and for the sake of animal shelters around the world to spay/neuter your cats. If you want kittens, get them from a rescue shelter. To answer the question, you can't make cats mate; they do it by themselves when the female goes into heat. 14 people found this useful.
