Has anyone made their own Neutralizer for the condensate tankless heater makes
 

I was just draining this outside but in this cold winter it makes more than I thought it would. I was considering just making my own acid-neutralizing device. Similar to this one.

I would make the container out maybe 2" PVC about 15" long. with screw on fitting at the top so I could refill it.

If it's PVC plumbing all the way, you don't need to worry. Otherwise, what you're suggesting should work nicely.

It is Pex but it just drains to the ground under my deck. I have two outdoor cats that would try and maybe drink that water. So I thought it might be good to neutralize it.
I am not sure if this would be bad for them or ever taste good to them.

Like Mike said you don't have to worry about your plumbing in this case.
My tankless heater is connected to the rest of the wastewater via PVC-plumbing (no metal). You could throw a few pieces of marble on the spot where it drains under your house of course.

Also you don't need to worry about your cats, this water is not like battery-acid or something. It's more like mineralwater with sparkles. If it would be harmfull to your cats they would taste that and avoid drinking from it.

Since it is not going to hurt my plumbing you have the best idea just buying a bag marble and putting a nice pile at the discharge site under my deck. This is not a covered deck rain easily gets to this spot.
