1. Inappropriate Elimination Behaviour
or Litter Box Use
Inappropriate and annoying elimination behaviors
by your cat can often indicate an underlying medical
condition and do not mean your cat is trying “to get
back” at you. These behaviors can include urinating or
defecating outside the litter box or other problems. A
cat with these behaviors may have any number of conditions,
including lower urinary tract disease, kidney
disease, urinary tract infection and diabetes mellitus.
2. Changes in Interaction
Cats are social animals and enjoy interactions with
their human family and often with other pets. Changes
in those interactions may signal problems such as disease,
fear and anxiety. It may also signal pain, which
can cause aggression.
3. Changes in Activity
A decrease or increase in activity can be a sign of a
number of conditions. Discomfort from joint disease
or systemic illnesses can also lead to a decrease in
activity. Increased activity is often seen with hyperthyroidism.
It’s important to understand cats don’t usually
slow down just because they are old.

day sleeping. The key to differentiating abnormal
lethargy from normal napping is knowing your cat’s
sleeping patterns and noting any changes.
