This all sounds like Misa and Sasa and Sasa and Franta.
Franta would just love to be Sasas friend but she hates him.
I cant touch Sasa but she loves Misa and him her. They dont snuggle together but Sasa seems to look up to Misa and wants him to go outside with her or come and play, he often ignores her pleading, which is sad,
When she went missing it was Misa who brought her home again.
The brothers birman used to cudddle together on the bed but when ducha had an op , franta stopped all of this and would not go near him for weeks and it took a lot of head butting by Ducha for Franta to even get near to Ducha again. This has lasted for about 18 months until recently and once again I occasionally see Franta part lying on Ducha, who looks around as if to say, well he is my brother
Intercat politics are very interesting
