Are you petting your cat and it suddenly bites you and runs away? Does your dog persistently chew your shoes, although it has a lot of toys?
Perhaps your pet is not being “naughty” at all, but is trying to say: “Master, you are doing everything wrong!”
For example, you feed him strictly on schedule, but pour food into a dirty bowl.

Imagine if you were served lunch every day on a plate that hadn't been washed for a week. Pets appreciate cleanliness too — they just can't ask for it.
Or another point: you buy expensive food, but forget that the animal should always have fresh water.
This is especially critical for cats, which are prone to urolithiasis.
And many owners ignore the need for “personal space” for their pet.
Putting the bed in a passageway where everyone walks or next to a noisy TV is a bad idea.
The animal will be nervous, because, just like you, it needs a place to hide and rest.
The most dangerous misconception is "he doesn't complain!" Animals are patient and often suffer in silence from pain.
If the dog has stopped jumping on the sofa, and the cat sleeps more than usual, this is not laziness, but a possible signal of health problems.
Don't wait until your pet starts limping or refusing to eat - it's better to take him to the vet again.
After all, you don't wait until your toothache becomes unbearable to go to the doctor, do you?
