In contrast to dogs, cats are more likely to present unwell. Again the clinical signs will depend on the anatomical location affected.

'''Alimentary''' cats will present with vomiting, diarrhoea, weight loss and anorexia.

'''Alimentary''' cats often present with vomiting, diarrhoea, weight loss and anorexia.

'''Mediastinal''' cats will present with signs of compression of structures in the cranial thorax. These include dyspnoea, coughing and tachypnoea due to compression of the trachea. Weight loss and regurgitation may also occur secondary to compression of the oesophagus. On auscultation lung sounds are displaced caudally and lung sounds are decreased ventrally. There may be a loss of compressibility ('rib spring') over the cranial thorax. There may be pleural effusion present. Differential diagnoses for a cranial mediastinal mass are: thymoma, thyroid adenocarcinoma, a mediastinal abscess, or a branchial cyst.

'''Mediastinal''' cats may present with signs of compression of structures in the cranial thorax or with dyspnoea from an associated pleural effusion. Signs include dyspnoea, coughing and tachypnoea due to compression of the trachea. Weight loss and regurgitation may also occur secondary to compression of the oesophagus though these are rare.

'''Renal''' lymphoma also occurs in cats and affected animals will present with signs similar to [[:Category:Renal Failure|renal failure]].

'''Renal''' lymphoma also occurs in cats and affected animals will typically present with bilateral renomegally and signs similar to [[:Category:Renal Failure|renal failure]].

'''Nasal''' lymphoma cases will present with dyspnoea, nasal discharge, epistaxis, facial pain or distortion and loss of airflow.

'''Nasal''' lymphoma cases may present with any of dyspnoea, nasal discharge, epistaxis, facial pain or distortion and loss of airflow.
