Clinical presentation is variable depending on duration and degree of exposure. Gastrointestinal signs (including vomiting, anorexia, diarrhoea and sometimes also abdominal pain) precede or accompany neurological signs (including seizures, blindness, obtundation, hyperexcitability, behavioural changes, head pressing, ataxia and tremors) (Zook et al., 1967; Knecht et al., 1979; Morgan, 1994). Clinical signs in cats may be more vague than in dogs and most commonly include anorexia, vomiting and seizures. Central vestibular abnormalities, including vertical nystagmus and ataxia, have also been reported in cats with lead poisoning (Knight et al., 2001). Clinical signs can be acute or chronic. In cases of chronic exposure, the seizures are intermittent (Bratton and Kowalczyk, 1989).
