Mo (the one in the pic) is more tolerant, though even she gets a bit biffy with Minx when she's too energetic. Lola has a shorter fuse & is very possessive with toys - I have to have words with her sometimes
both of them will play mad-chasing with her when in the mood (up & down stairs, in & out of cupboards etc)
both will let her share their food dishes, which is amazing; though I generally take her away & point her to her own
they haven't yet started baffing her, or curling up together, but they do snooze alongside. My PC is in front of the bedroom window, & this afternoon Minx & Mo were on the sill (it's a very deep sill with the radiator underneath the overhang, extremely cosy) with Lola beside me on top of a pile of boxes - really matey
Awww, TheOne, that's just melted my heart....<wibbles>
My big cats are are a bit like that - LittleFluffyWhiteCat hisses and spits at them still but there's no real venom behind it so they just ignore her and roll their eyes!
BigFatPatchyCat, on the other hand, has been spotted getting snuggly with them and with Fudge in particular; she's also been grooming both kittens quite a bit. It's all very luffly and heart-warming to watch...
Still no home for Fudgey, but am constantly telling people about her. Hopefully she'll get a forever home soon.
