why my cat cannot sleep ?

my kathy cannot get in to sleep after i have sent her to vet cause her ears got infection and the vet gave her an injection which is antibiotic and after she came home . she was normal but cannot sleep ! she will sleep like a pig b4 tat ...... i called the vet and he said bec she is painful so she cant sleep but when i see her . she seems to be fine ......

but why ?


im worry about her ...............


thanks

She may look just fine but you have to think animals wont show as much as humans do when they are in pain its a sing of weakness ... how long has this gone on now... try to have her sit in your lap and just pet her she might be able to sleep then...just something to try
