Three years ago we adopted a beautiful rescue moggie. She was 2 years old. The rescue centre said that she had been a house cat who wanted to explore so owners gave her up. She's been happy and settled, loving, kind and gentle with the tweens. Not a lap cat but loves strokes and one of our children in particular.
When we adopted her they said she could live with the kids and a dog (we don't have one and she avoids MIL's) but not other cats.
Given she is top cat and settled here, would the arrival of a rescue kitten be a huge no no? I wasn't sure whether cats adapt or whether she would hate this and we wouldn't do anything to harm her physically or otherwise. Any advice?
TIA.
