No poop but everything else fine

Hi all, I have a cat who is eating, drinking, playing, in a good mood. I dont see her in pain, or straining but she hasnt had a poop since sunday..so thats 4 days. I bought Laxapet from Amazon, not sure how long it takes for it to kick in. Because she is fine with everything else, should I worry?

Hello - that is surprising.  How do you know that your cat hasnt pooped - out of sight?  Are they trying to pass something?  I wouldnt advocate giving these products because they are not simply a treatment for 'not pooping' - and could make a healthy, comfortable cat ill.  Rather, you should call your vet who will triage the case and help you to decide the next most appropriate step.
