My cat is 15 - she has an underactive thyroid and congestive heart failure but this is well managed with medication and she still seems fairly normal and happy in herself.
My issue is that she won't leave me alone... she's always liked to sit near me and next to me and sleep on the bed which I don't have a problem with but now she seems obsessed with actually sitting on top of me the second that I sit down. I WFH and she wants to be on my knee while I'm on the laptop constantly and rather than sleep next to me in the bed like she always has done she is insistent on sleeping on top of my leg or even on my back which gets really uncomfortable for me! She also then gets upset and yowls if I mover her away from me. I feel awful moving her but I have stuff to do!
I have just been away for three weeks (she was seen twice a day during this time) so I didn't know if that could be it but it's been two weeks since I've been back now and my other cats have been exactly the same since I came home...
