My older boy cat I've had just about a year (I was told he was 7 when I adopted him from a friend of a friend who was going to put him in a shelter, but vet says he's more likely closer to 10) has in the last week or so become very clingy. I thought maybe he's cold but he wasn't this clingy this time last year, although he's always loved affection. Now though he wants to be in my lap constantly and if I stand up to make a cup of tea he waits for me to sit down again or stretches up on my leg to remind me he's there waiting for cuddles. He's in my lap right now!
Should I be worried?
