It depends on what you mean by "need to have a mate":
Yes, cats need to mate to become pregnant.
Female cats, however, do NOT need a "mate" (i.e. a male cat) to raise kittens. Males only mate with females. The female gives birth to the kittens and raises them.
Well you would like to know that because you want to know if the cat is going to get pregnant or get another cat pregnant....
Then you will have to bottle feed the kittens or get another cat with kittens to do it. You can ask a vet if you need kitten formula. A pregnant cat will usually not show milk until soon before she gives birth.
A cat can get pregnant as soon as a few days after giving birth, so it's important to keep her separated from male cats to prevent another pregnancy.
Only through deep bite or scratch wounds where the saliva of the cat who is infected enters the other cat's bloodstream, or from pregnant cats to their offspring.
No, a cat did not jump on my pregnant belly.
Yes, I've have had a cat that purred while she was pregnant.
No, a cat will not go into heat if she is already pregnant.
What? another answer: thats not even a question
Yes. In fact, that is the only time that a cat can get pregnant.
A cat is able to get pregnant as early as 4 months of age.
No. Animals can only get animals of their own species pregnant. A dog can only get a dog pregnant, a cat can only get a cat pregnant, etc.
A cat can get pregnant within 24-48 hours after mating.
