Objective—To determine duration of administration,
complications, and frequency of aortic thromboembolism
associated with administration of low molecular
weight heparin (dalteparin) in cats.
Animals—57 cats treated with dalteparin.
Procedure—Data were recorded from the medical
records of cats treated with dalteparin, and owners
were contacted by telephone for information regarding
ease of administration and possible adverse
Results—Dalteparin was easily administered by owners.
Median dose was 99 U/kg (45 U/lb) once or twice
daily. Bleeding complications were infrequent. Of 43
cats with cardiomyopathy that received owner-administered
dalteparin for a median follow-up time of 172
days, 8 cats developed documented or possible arterial
Conclusions and Clinical Relevance—Dalteparin
was easily administered by owners and was well tolerated
by cats. Whether dalteparin administration can
reduce the frequency or severity of arterial thromboembolism
is not yet known. (J Am Vet Med Assoc
