Cat Behaviour Set Against Possible Health Problem
This is a truncated, compact chart showing a list of possible health problems resulting in certain kinds of feline behaviour/symptoms despite a cat’s skill at hiding illness.
I think that it is quite useful, although it is limited. The list could provide some ideas to people as to what might be going on if they spot these sorts of behaviour patterns/symptoms in their cat. The list comes from Dr Bruce Fogle, the well-known British veterinarian/author.
Any of the signs on this list warrants an immediate trip to a veterinarian.

Cat behavior set against illness
Provided a cat caretaker is diligent in taking their cat to the veterinarian as and when required, I think it is useful to have some knowledge about cat health problems as it informs the cat caretaker, makes them more aware of what is going on and it can also help the veterinarian in diagnosis.
