I have a three year old Calico cat and a 10 month old black cat. The Black cat (Gizmo) is the Calico cats (Holly) baby. Holly was an excellent mother to her kittens, after we gave away all of her babies except for Gizmo, she continued to let Gizmo suckle from her until Gizmo was around 6 or 7 months old, Even when she began to ween Gizmo, Holly would continue to bathe her, but recently she seems to want nothing to do with Gizmo anymore, She used to play with Gizmo, but now when Gizmo makes a gesture to play, Holly will either growl like a little dog (and it sounds just like the growl of a small dog, its funny) or she will slap at Gizmo. I dont understand why she would turn on gizmo so quickly, can anyone give me an answer or good guess at this?
