I'm finally starting to think that adopting the girls was the right thing to do, this is in part due to a recent post by someone on CatChat in response to someone asking if their cats were happy
A happy cat will walk around the house confidently, tail held high. They will come to you demanding fuss and attention (and treats). They will sleep out in the open or with you if allowed, some will sleep in a sprawled position rather than neatly curled up. they will be interested in what you are doing, and just wanting to be with you. They will spend time looking out of windows watching the world.
An unhappy cat will want to hide, they will find a dark corner and withdraw to it. They will refuse social interaction, possibly not even taking a treat when offered. They will sit in a tense hunched position, barely moving. They will eat and drink less, lose weight, and their coat will lose condition, they may start to over groom and end up with bald patches. When they do move out of their hidey hole they will slink around belly down, tail down, keeping to the walls.
While the girls don't do all the things on the happy list, they do enough for me to realise that they are content with what they get. Ironically Coco can be demanding without making a noise - last night I came in to give them their supper and got distracted on the internet (it was their night out, so the door was open), they both left the room, she came back after a few mins and looked a bit put out to see no food, then after 5 mins came back in and just sat staring at me!! Then ate some of her supper off my hand. Not used to cats who can demand things without making a noise, as they have Siamese in them, I did say I was grateful they don't make a noise! I had both of them watching me brush my teeth, Coco actually laid down with her paws under her watching me! This morning I got up at 5am to make a cup of tea, Chanel was curled up on the stairs, and actually let me walk past her, which is a first, Coco was on the sofa and she also let me walk past her (not a first, she's done it a few times this year). I do think a lot of it is down to lockdown and having more time to spend with them. Me and my neighbour were talking the other day, she thinks they were sent here to help me with giving up volunteering, which I agree with, as I've been able to keep the routine I had when I was fostering, just with added time at a weekend and being forced to go to bed earlier and stay in my room longer on the weekend day they are out, which has been especially helpful during lockdown.
