The only pet I had for any length of time as a child was a hamster. But I never really fed it myself unless I felt like it. And it got lost.
Meanwhile, my cat Ezio, whose welfare is entirely in my hands and therefore makes me infinitely more invested and attached:
Ezio is one of two cats I take care if who do nothing but eat, groom, watch birds, and lounge around.
The other one is Simba:
These two freeloading houseguests with bottomless pits for stomachs have taught me how to be responsible. And I am filled with love and affection for them.
Life with cats.
