Is it kitten season or something?

So my mum just called me and told me that a mama cat is living in her laundry area behind the washing machine and air con compressor with her four tiny kittens. Mama's a tortie, two kittens are torties, one kitten's black and white, and the last one is white with marmalade patches.. oh boy. apparently mama cat is super duper feral. i better investigate..
