Filou and Tigris are 8 years old so I don't think of them as seniors but some of the developments you described I started to notice as well.

Both were not the most people friendly of cats and Filou shows his precious self even less than he used too. He will be a grumpy old man I suppose but being an Aby he still is very good in jumping and running.

Tigris however came closer to us humans. He loves to be in the middle of parties. Last year when Randi and John were here we were all surprised Tigris came over and accepted being petted by John- but this year we think it is normal that he asks visitors for attention

Both look gorgeous- Filou on the thinner side and Tigris being a handsome hunk! I hope to share my life with them for many years to come
