Ragdoll Josie grew up around Golden Retriever Lucy.
The two are so bonded, that the new mother couldn't wait to introduce her kittens to her best friend.
The sweetest pair
"Josie has always trusted Lucy", explained their owner as she shared the clip to TikTok.
And as the video goes on, their deep trust and understanding is the sweetest thing. Josie lies with her paw resting on the senior dog's leg, happily letting her sniff her babies.
Viewers praised Lucy for her gentle greeting of the kittens.
"Proud mamma and lovely bestie", commented a viewer.
"The dog is being so respectful", wrote another. "She wants to wash them babies but doesn't want to overstep. My dog was the same with ours. They adore her now too. She's the step mum, not me".
"So special"
Lucy and Josie's special interaction melted the hearts of animal lovers everywhere, with over 2 million viewers liking the clip.
"She loves that dog. Showing her belly and everything. Cats only do that when they're feeling comfortable", explained a viewer.
