I do for everyone as long as they keep in touch. that way I know they're interested about my pets.

crayola, my law dog from SPCA service dog program, they mail out an annunal evaculation form, checking on if I'm still 'using' him accordly. of course I do, and still treat him like my companionship but if I don't respond, they'll take him away as, unforunately to say, it is federal's dog. they're great people (who has their dogs themselves too) to keep in touch with anyway.

cats, ah, I'll try to keep this short...lol.

zephyra's rescuer who found her outside of her backyard - we keep in touch with pictures once/twice a year.

ocean and miles, they both came from SPCA shelter. I sent a thank you along with first/last update of ocean (3 years ago now), they still have that card hanging up there! he looks much the same anyway, ha.

eclypse and clayton who came together, their rescuer's the owner, we keep in touch with the most. we're more like friends. we talk and even send personal pictures to each other every other month or so. oh, and the little ark always gets a christmas card from her and her different fosterkids.

shaddow - from my 'big' sister (friend) who moved into no-pet allow home, we talk weekly.

whispers - from a box. abox doesn't talk!

midnight, from lost SPCA, which is no longer there now where I used to volunteer at.

star, I rescued this dying girl out there on a street one night, no information of herstory on her so as well as she had her four boys, gus, (rainbow) avalanche, chance & echo three weeks later. and yes, I do keep in touch with myself!
