Fresh spay incision   

What's the first thing to do if you find a stray animal and you take it home? (Especially if its female)

- - - - TAKE HER TO THE VET! - - - -

 Many stray females are discarded BECAUSE they are pregnant. Also, if you have resident pets, protect them from disease by promptly vaccinating the stray. While at the vet, get the stray fixed.  Long haired dogs and cats hide pregnancy well, so don't take a chance on a surprise litter. (Ask your vet for a 'rescue' discount.)

If you locate the owner of the stray, ask them to reimburse you for the vet bills and insist they tag and contain their pets. Fixed pets stay home better too!
