Puppies can make them feel a little out of sorts but I would be more concerned that you are seeing a urinary problem. Urinary tract infections and urinary crystals that cause blockages are common causes of problems in cats.
I suggest that you see the vet for a urine culture to rule these out and then proceed from there.
If the cat has "sand" in the urine, this can cause a blockage and this can be potentially fatal.
Let me know if you have more questions about this.
