I have known of cat with hemo that had to be on the doxy for *longer
than 6 weeks*, only my opinion but I would put him back on it. Has he
been checked for Ehrlichia? Please make sure you vet is aware of these
possibilities, talked about below.
Here are some links to some of the causes of feline anemia:

Some other causes:
*Feline Haemobartonellosis* is the most frequent cause of anemia in
cats either as a primary or secondary opportunistic disease. (A cat
with another disease such as feline leukemia will be more
susceptible.) The prevalence of the disease is higher in male and
outdoor roaming cats. It can be transmitted by ticks and also can be
transmitted from an infected queen to her kittens. Symptoms can
include sluggishness, depression and a lack of appetite that can
become severe.
*Feline Babesiosis* is a disease caused by a strain of a Babesia
protozoan microorganism. The tick "Rhipicephalus sanguineos" is the
culprit for this one. Signs to look for include fever, anemia and
jaundice.
*Feline Cytauxzoonosis* is a disease in domestic cats that causes
severe anemia and can be fatal. It is transmitted by ticks and mainly
by the "Dermacentor variabilis". Cats with access to the outdoors are
at a higher risk of this disease and, if infected, can exhibit fever,
loss of appetite and depression.
If caught quickly, these diseases can all be treated, so keep a keen
eye on your pet and talk to your vet about any sudden behavioral changes.
