Blanca has become a bad momma cat

I do not know what is wrong with Blanca.  She was a good mother from the get-go.  She nursed her kittens way beyond what most momma cats do.  However, two weeks before I had her fixed she turned on them and would hiss and claw at them if they came near her.

I figured this would cease after she was spayed but that has not been the case.  Paquito (my favorite of the litter) was the one most attached to her and she clawed him in the only good eye he has left and I had to rush him back to the vet a few weeks ago.

I thought we had come to a truce. Her three kittens (who are not kittens anymore) would stay in the back porch by the kitchen door and Blanca would be by the front of the house where I bring her in to feed her in the enclosed front porch.

It worked out for a while but if I came back late in the afternoon...which I do all the time...they would all be waiting for me in the front yard and then all hell would break loose. These darn cats are training ME instead of the other way around.

If I feed the kittens first, she gets mad and comes and eats their food and of course, hisses and claws at them. The other two have learned to avoid her but apparently, Paquito has not. The last thing I need is to have him lose his eye and be left for blind.

All my life I have had male cats (one at a time) never female except for one I adopted after the people that rented across the street moved and abandoned her.  I even had her fixed only to lose her after a car ran over her shortly afterward.

Walter is still not back in his stable.  I am wondering if they sold him or he passed on.
