My male cat is calling to mate. Should I get him a female or neuter?

I would not recommend bringing in a stranger cat to mate with your male. Not only will it cause stress for Habia who has a litter of kittens to look after, but you could be creating another litter of kittens with this mating, which is not responsible breeding unless you are planning to look after this female and her kittens as well. In addition, allowing him to mate this time will not stop the calling, he will continue to call because this behavior is hormone driven. The only way to stop the calling is to have your male neutered, which I would recommend.

I would keep Lazgah away from your female and the kittens. Some tomcats will attack and kill the kittens as a means to get the attention of the busy mother away from them. I would not allow him to have any contact with her or the kittens until the kittens are weaned from their mother.

Unless you are positive you can help your friend find a proper home for every single kitten, I wouldn't recommend mating him. There is a great over population of pets in our world, and un-purposeful breeding shouldn't be allowed. I would recommend getting Milo neutered for his own health. I promise, he won't think he is missing out on something in life!

Cats who are not neutered are generally more interested in fighting and breeding than they are their human family. I recommend to have him neutered as there are many health and behavioral benefits: https://www.petcoach.co/article/benefits-of-neutering-castrating-male-cats-kittens/ I hope this helps.

I see that Lucifer isn't neutered. More than likely, he has reached sexually maturity, and wants to go out to find females with which to mate. Probably soon he will start urine marking in the house to mark his territory. Even letting him out to mate will not stop the behavior, it will continue. If you want to stop this behavior completely, have him neutered. Best of luck.

I see that Casper is a little less than a year old, and he is also not neutered - so I'm afraid this is very normal behavior. He is just now reaching sexual maturity, and as long as he is not neutered, he will be very motivated to roam and look for female cats. There is nothing at all you can do about this apart from having him neutered, so I would recommend doing this as soon as possible. You will both be much happier once this has been done :)

Bringing an intact female into the house will likely cause aggression issues between them, so you'd have to keep them separated when she is in heat. If you only want to breed one of them, then I would have the other neutered before bringing in the female. I hope this helps.
