152 PRACTICAL RABBIT KEEPING 



Coccidiosis. — Probably much mortality 

 among rabbits for which the owners can find 

 no reason is due to this trouble, which is 

 caused by parasites which are pretty certain to 

 develop wherever there is an accumulation of 

 filth which is not promptly removed. Perfect 

 cleanliness is a certain preventive. One objec- 

 tion to the stacking of hutches in tiers is the 

 increased danger that they will not be kept 

 clean. Urine sometimes seeps through the 

 floors into the hutch below. The reason that 

 rabbits cannot be kept safely for more than a 

 short time in an outdoor yard with an earth 

 bottom is because of the trouble likely to be 

 experienced by the presence of coccidia when 

 the ground becomes foul.
