Since we've starting letting our indoor cats out, one of them keeps coming home with her fur in clumps sort of underneath. if you stroke her, some parts feel bumpy.
I've brushed her but it doesn't get them out and I've resorted to cutting the clumps out which is making her patchy. There doesn't seem to be anything in the clumps that I've cut out, although she is also getting burrs caught in her fur as well.
Should we just keep brushing her every night to try and preempt them and cut out ones that can't be brushed? Does anyone know why she would suddenly start getting them?
