sandyballs,
With eight cats we have used a couple of lovely local catsitters over the last few years and I also run a simple website for a friend who runs her own catsitting service (not near enough for me to use worse luck)www.purrfectsolution.co.uk
Things I look for in a cat sitter are :-
: Friendly person, who gets on with my cats. I must meet the cat sitter in person so I can show them the house, fill out their paperwork and I can see how they interact with my cats.
: Up to date public liability insurance, in case of problems in my house.
: Vet reference (i.e. from a vets about the cat sitter being reliable and good with cats, most catsitters are or have been pet owners)
: Past/current Customer References preferally phone numbers so I can check up myself. These can include friends and family but be clear that they are friends/family when giving out references as it looks better to the potential new client.
: Good key security. i.e. Keys not labeled with clients name or clients address use a code number instead and all keys must be kept in a locked safe at night.
: Good home security. Park outside neighbours house and/or no advertisment on catsitter's car else you are telling everyone that the house is empty. Offering to turn on/off lights and close/open curtains, pick up milk/mail as part of the service.
Other stuff...
It is common to charge per visit. Though I expect to pay more with the number of cats I have but to date I have only been charged the standard rate of £15 for 2 visits daily.
As for vet bills, I would ask the clients sign a standard letter which you can send to their vets which says "I authorise {name of catsitter} to bring my animals for treatment in my absence and I promise to pay in full for all treatment asap" Then the bills will go straight to the client and not you.
Also charge 15% on top of cost for anything you need to buy in case the owners run out..catfood and litter etc. The additional 15% should stop people 'forgetting' on purpose.
It might be worth getting together with another local catsitter to cover each other in case of emergencies and/or holidays. That is my main concern with a 'one man band' catsitter and if a family member is going to help out in an emergency, I would want to meet them too.
Also if you are or could be trained in giving medications and specialised treatment like diabetic care there is a lot of cats with medical needs and you could proberly charge more for those cats.
Sounds like a lot to cover but when you are talking about your home security and beloved pets health you have to be careful and once you have got yourself a new client, they will come back time and time again.
I'm sure I have missed some stuff but that is the basics.
