We have had Cat1 for just under 2 years, she was around one when we got her. We also have another young rescue cat who is 1.5. The girls tolerate each other, play chase etc but aren't besties. They are currently indoor cats (Cat1 has always been indoors, Cat2 was born feral) but planning to secure our garden to start letting them out in the summer. We live near a busy road so not keen to let them roam free.
In the last couple of weeks Cat1 has started gently nipping us. She doesn't hurt or bite hard, it really is very gentle. But I find myself now tensing whenever she approaches as even if it doesn't hurt it's not pleasant either.
Why is she suddenly doing this? I initially suspected it is some sort of affectionate behaviour as she does it with my DH more than with anyone and she absolutely adores him. But now I have just seen her go to Cat2 when Cat2 was asleep and gently nip her cheek, they never groom each other or sleep together. She went into an ambush position after so maybe it was an invitation to play or attention seeking?
Just trying to understand why she has suddenly started doing this, and how can we get her to stop it? She's never hurt anyone but it's just not a nice thing to do, especially as we have kids and their friends often visit.
