Definitely very busy, the shelter ours came from must have 40 kittens and 10 adult cats, not to mention 20/30 dogs, half a dozen ponies, etc. Our second kitten will be with us on the 7th September, it's not from the same litter and must be a couple of weeks younger than our ginger female. Got them from here.
