Although cats can’t (or won’t) speak, that doesn’t mean they can’t be expressive in their communication. The only trouble is that you have to decipher their physical movements to determine what they’re trying to slay to you.
Purring can be a sign of contentment but it could also mean they don’t want you to move. Also when cats rub against you, that’s a form of cat hugging, which cats do in the wild. So when your cat wraps its tail around your leg, that’s its way of hugging you and saying it missed you.
The next time your cat does anything, study its movements carefully. Whatever your cat is trying to tell you, it’s a safe bet that it wants you to spoil it and devote all your time to making it happy while you do all the work so it can enjoy the benefits.
