Feral cat will be coming inside

Hi! I am new to The Cat Site and don't know my way around.  I will be bringing in a feral cat that I have been feeding for the past year. In fact, now I am feding 4 feral cats. I live in a mobile home court and my neighbor hates cats. She has turned me into  the office for feeding the cats. She says the cats poop in her yard and her yard is not a litter box, so every morning I go over and pick up the poop. Now the office has set up live traps to catch them and take them to the pound. We do not have a no kill shelter here. I can't bear the thought of any of these babies being captured but the one is a big unneutered male who is a big teddy bear. I will take him to my vet to be neutered, lab work etc. How do I introduce him to the 4 other cats I have inside. One of them I have to separate as she doesn't like other cats and most people.  Thank You

Adopted ex-homeless are often (not always) rather submissive to the residents.

They also are usually used to interaction with other homeless cats, so they usually do easily settle in.

Easier than say, a bough home raised cat.  (exceptions do occur like in a parallell tread, but they ARE eexceptions)

The big exception are territorial, dominant toms. These can be nice to people (and thus going adopted) but are horrible to the residents, beating them up...     So in this case, you must neuter him at least several weeks before any introduction attempt.  And do a slow "scientifical" introduction. Lotsa treads in the Behavior forums are about introductions.

Shy or cat friendly toms are easier than these territorial ones..

So, do you know how he was with the other cats till now??

About your situation. You do quite right to pick up the poo in your neighbours garden.  You can perhaps lay out some real cat litters?  If they are de facto your outside cats so...

Talk with her again and again, friendly and diplomatic.  Also with the personal in charge.

Tell what you are doing. Tell, if they homeless got neutered all, there will be less disturbances.  They will still do some litter things. But they wont example any longer pee everywhere on everything.

Remind them, a well kept TNR:ed (neutered) colony will tend to held back other  homeless coming in.

And, before all, will also keep rats and other rodents down.

So the key is, neuter them...  Look up the TNR.

etc...
