I've got a small dog plus a cat who moved in years later after the death of a relative. Ddog is very gentle and submissive with dcat, a bit wary of her but on the whole they peacefully co exist and both sleep on my bed. Dcat has always been ok with ddog, a little tetchy at times with her claws but tolerates her well.
Today they were together on the sofa and for the first time dcat started rubbing her head all over ddogs head. I was prepared to move her away if she got tetchy but she just wanted to rub heads lol.
Is she showing love to ddog? Or just marking her scent on her?
I found it so sweet to watch. Ddog was having a bad day with her dementia so it was quite nice really.
