About the same size as my Marble...very nice pics...I hope you find a solution to the Rinoa issue.....and I am glad my Kermit (twice their size) doesnt pick on Marble....she chases him.....So did CC but we created a sanctuary...(our bed or near us). and they both learned the meaning of the word...CC could be rough, as he was ten when Kermit was a kitten...rough play, not maliciious tho sometimes we weren't sure. So, when Kermit made it to us (the bed or couch), there was no more issue as we called out 'sanctuary' and CC knew he could get swatted for not following this rule. It was surprising how quickly they both caught on....it helped that wife was a stay at home mom and the kids enforced this rule too. good luck.
