I'm sitting here trying to type but one of my cats (who likes to settle down on my work station to watch me in the evening) keeps asking for a stroke.
I've grown up with an assortment of pets from dogs,cats, guinea pigs, rabbits, bird and even rats. Each and every one was completely different, just like we are.
They are company, a source of amusement (and sometimes exasperation!) but teach you about putting something else first, compassion and give and take. I've had cats who are up themselves and ones that think they are dogs (even one who sat on my shoulder like a parrot). I do miss having a dog but I work full time so not an option. (my mum used to say anyone wanting a child should have a puppy fist and see how they can handle never having a moment alone again!)
My partner was very anti cat but now he keeps dropping hints that he wants another kitten!
Cats are a bit like teenagers if you want to compare them to anything, they can be aloof but when they want a cuddle or a snuggle they will come looking for you (a bit like we would).
Children could also be described aslong term leeches, longer in fact than a pet is and they take years to potty train
You need to be mature enough to own a pet, have empathy and not be selfish as they rely on you (and we in turn rely on them for company and fun)
