The Lions’ Den was the first fully licensed cat boarding establishment in the London Borough of Hounslow. It is conveniently located close to the M4 / A4 and is ideally placed for the London Boroughs of Hounslow, Richmond and Kensington & Chelsea also giving easy access to Heathrow Airport. By virtue of The Lions’ Den’s proximity to the M4 there is easy access to the M3 and M25 making the journey to Gatwick a breeze after delivering your cat(s) to us.
