If you pay for spaying, deworming and vaccines - which may be wise, so you are sure its done - simply ask for refund of the spaying money... The adopters will be happy, so they dont need to trouble with it themselves, Which I think is one of the reasons many dont let spay their cats. Not always money, but the trouble. You must fare to the vet at least twice just for spaying. You must have some postsurgery care... Lotsa troubles for someone you got for free.
my mom already got few people who wantsone that she knows but since i don't know who they are i don't know whether or not i should demand money from them too
And or, you can always ask for an donation to some nice praiseworthy cause, in the CATS name. Or if the cat is called say, Snowflake and the family is Johnson, from Snowflake Johnson.
It causes even a magical bond, making the cat as part of the family, and connecting the cat with noble feelings: helping a good cause without even clear advantages from it,
Tell her its advices you got here from this forum...
are there other any tips to finding good homes, my mom have problem demanding money how do i convince her? she also say i need to stop having all these rules it not my fault that i care for them deeply,
Of course, if she know these people personally, and does quarantee they will be good homes, there is some place for maneuwring. Good you too learn these people. Its more difficult to do shameful things, or irresponsible things, if they know you will know...
I hope you understand my english. English is my third language.
Good luck!
ps. Re books: Begin to read on our site, both articles and the threads in the Forums. There is a great lot of good info, partly buried in there.
