Re: Doxycycline in cats
According to The Pill Book Guide to Medication for Your Dog and Cat, the doxy dose for cats is 1.4-8.25 mg/lb orally twice daily.
Here is some additional info on doxy from this same source.
" ... should not be used in pregnant animals as it can retard bone growth in the fetus and discolor teeth ... will cross into the milk of lactating animals and should be avoided ..."
"... it should not be used in the young puppy or kitten."
" ... can be used with care in older patients with normal kidney and liver function."
Common side effects are, " ... symptoms relating to the gastrointestinal tract, nausea, vomiting, diarrhea, and loss of interest in food. Cats ... may exhibit stomach pain, fever, hair loss, and depression."
Rare side effects include, " ... photosensitivity, liver damage, and changes in blood cells."
"Chronic overdoses may result in kidney damage."
"Doxycycline is well absorbed even with food in the stomach."
If your cat is taking any other medications, let me know, as there is a list of potential drug interactions.
