Birmingham is experiencing a severe rat infestation, with residents describing the rodents as "the size of cats." The issue is attributed to a bin strike and ongoing HS2 construction near the affected areas. Birmingham City Council introduced a £24 charge for rat control visits, referred to as a "rat tax." Residents, including Kim Blakeman and Mariya Malik, report significant disruptions, with rats damaging property and causing anxiety. The council acknowledges the problem and assures at least one weekly bin collection, while treating rats at a contributory fee. HS2 emphasizes prioritizing health and safety.
