I think our cat was picked up. Where should I go to find him? He's been missing for about 4 days.

Not to burst anyone's bubble but theres bo such thing as a "no kill shelter" they euthanize animals daily. Call San Antonio Humane Society on Hwy 151. They are the main location and should be able to get you contact info for other locations that may handle your area

You can try animal control services@ 4710 TX-151 ,S.A TX,78227. Hopefully your cat is there because it is a no kill shelter. Hope you find your missing feline friend
