Cat care service involves:
Spending time to see if he or she is acting as normal as possible with you away. If your cat is not interested in a little pampering then I will not intimated them by trying to stroke them but observe them from a distance to check that they are feeding ok.
Daily cleaning of food and water bowls.
If they use a litter tray then this will be throughly cleaned daily.
Give any medication if required, tablets, injection or anything else is fine.
Grooming if your cat will tollerate it !
