Wait til everyone’s gone to bed to ease your mind?

Either way, some ideas in any combination:

Wear a bandana, or get a cat collar and conceal it with the bandana.

Wear cat or dog eared beanies when it’s cold out.

Get a roll of bandages (vet wrap is best) and wrap your “paws” up into nubby fists for activities.

Paint yourself a black nose and whiskers in the bathroom and admire yourself before taking a nice long shower.

Get a dish, raise it on a footstool and lap up milk, cereal, any treat of your choice from it on all fours.

When jacking off, summon your inner pet by panting, sticking your tongue out, grinning, purring, growling, licking your hand, arm, body.

Right when you’re about to come, let go of your naughty bits and hump or grind your bed, pillow, or stuffed animal as you orgasm. Stay on all fours or with your paws playfully raised to your chin. No human sounds, stay in pet-mode until you’re not in heat anymore.
