Hi Chels22,
We've recently started a new comparison site for pet insurance, I think it may help you in choosing the best policies for your new puppy and cat -
Compare Dog Insurance &
Compare Cat Insurance
Look out for the multi-pet discount if you're looking to insure them both with the same company. The other point to note is the Defaqto Rating, this is an independent research company that rates the policies on a star system.
Hope that helps!
