I am a vegetarian, but I do not want my kitten as a vegetarian or vegan. Where can I get cat food from organic and free range meat or fish taken, preferably dry? So what is the most environmentally responsible, and cat litter that is environmentally degradable throw for me?
If possible in London or on the Internet with cheap shipping?
