Im not a rescue centre but I do take animals in and rehome them, I only advertise in veterinary surgeries and on rescue websites such as rabbit rehome for example.
My reasons are that if someone is at the surgery already it kind of indicates that they do take their other pets to be treated (always a good sign) and I can discreetly ask the surgery staff for a little background, nothing personal, just 'are they regular clients', 'do the animals seem well cared for and problems they have been in for are not in their opinion down to bad animal husbandry or if it was did they work to change the way they cared for the pet'
With the rescue ads I feel people that are looking here have gone out of their way to find a suitable pet and aren't just browsing through the paper or passing a shop window and on spur of the moment a pet would be cool and not thought of the time, effort, money and love it needs.
You don't have to neccessarily need to hand over the buns to a rescue and burden (usually) an already overrun homing centre. You can ask them to forward your details to potential owners if they do not have what the prospective owner is looking for.
The main things you need to do where ever you advertise is:
Home check and follow up checks
Draw up a small adoption form entailing yours and their details and a statement confirming that they shall neuter and vaccinate as reccommended by a vet and in bold IF I THE UNDERSIGNED NEW OWNER CAN NO LONGER FOR ANY REASON CONTINUE TO CARE FOR THE ABOVE ANIMAL, I AM LEGALLY BOUND TO RETURN THE ANIMAL TO ........(your name) TO BE REHOMED.
Ensure they are aware of the responsibility both financially and spatially.
Just go with their reactions when you tell them the cost of neutering and vaccs and insurance etc...
There is no reason for you not to do the above, you dont have to be a registered rescue to have an agreement, Ive done this for years and its a safeguard for the animals future and to this day I have always had owers come to me first with any problems they have had or if they cant keep them any longer. Its great peace of mind
As for donations or charges thats totally up to you, I nearly always ask for a donation because unless the animals are too young I get them neutered or vaccs and I certainly can't afford to not ask!
If they are babies I would just rehome free of charge not being a rescue centre as they have to pay out for the above in a short time so as long as I see evidence at the next follow up visit im happy
Wow I waffled on there didn't I??? Sorry!
Anyways GOOD LUCK!!
Give them this website to look at!!!!
