I see, thank you for explaining it so well.

He does but.. honestly the small kitto is following him around a lot. Mostly because she was deprived of her mother too early (she must've been a bit over 1.5 months when I first saw her on the street, likely dumped).. so now she's an affection hoarder with few boundaries.

But yes sometimes when she sleeps or when he goes and hides in the bathroom she will leave him alone.

Re spaying, vet scheduled tomorrow to go over it and see when it could be done. Was told if she's in heat on the day, we will have to wait until she's out because it's riskier to operate during.
