So we are at a campsite and yesterday a lovely and friendly cat came over, he came in to our tent and he was so friendly I assumed it was the campsite owners cat. We fussed over him and he loved all the attention. It turns out it wasn't the owners cat but apparently it was a stray cat! Well now I'm worried it might have had fleas and dropped some eggs in our tent. How likely is it and how do I avoid them getting into our home when we come back from here?
