My cat is 18 months old now and started off with being so cuddly as a kitten, used to carry him around all day (am a wheelchair user so this was easy) Recently (over the past few months) he has started to avoid sitting on my lap at all, he will deliberately go round me if I happen to be in his path. He still comes to me if I or he has been out and will still sit with me every evening but just leans on my shoulders and doesn't purr like he used to! He still sleeps on my bed at night. In the past couple of weeks he has even started to avoid being picked up by making it more difficult for me.
If he is just being a typical cat that's fine but just wondering if it's something I should get checked at the vet. I Hate to think of him being unhappy at all and he used to be so affectionate.
