Hello! I used to frequent these parts a lot back in the day, but I haven't been around for a while. This is Tiny (on the left) and Simba (on the right.) I brought them home from a rescue centre back in 2012 after their previous owner passed away. I don't know a lot about their history but they're unrelated. Simba is roughly 13 and Tiny is 7-8 years old. They've lived together for a long time now (probably since Tiny was a kitten, I reckon) and for the most part, they've got on very well. They eat and sleep next to each other and occasionally groom each other. However, lately, skirmishes appear to be more one-sided and frequent. I'm inclined to think Tiny is play-fighting like a kitten. He will sneak up on Simba, hide behind something and ambush him, gently biting him on the neck, leading to Simba taking ever more circuitous routes around the garden to try to avoid any sudden nasty surprises. Unfortunately, unlike a kitten, Tiny weighs about 6kg and can send Simba sailing through the air with very little effort. Simba's got a lot more vocal over the years, and will hiss and growl when Tiny does this. Is it a shifting of the power balance as they age? Has anyone else experienced this with two cats that have been together a long time (like an old married couple)?
