Yes!

Of my current 3 cats:

• 16 year old queen of the house, the best lapdog of all time, gotten from a shelter 13 years ago along with her bother (very recently deceased)
• 13 year old from the same shelter, dumped on us when daughter moved out of the country with limited notice and didn’t care where said cat ended up. Horrible bitey monster, but not letting her die on the streets or in a shelter
• 1 year old who wandered up to my back door in October, starving and quite obviously pregnant about a week or two after we started feeding her. Now sleeping on HER ottoman in the front of the house, very content

Every single cat I’ve had as an adult has been from a shelter, a stray or the product of a stray.
