I know this answer isn’t tea or coffee, I don’t like coffee and I gave tea up because it was staining my teeth.
I was on herbal teas for a while but I then had the idea of drinking a weak beef stock (1 stock cube to 1.2 litres of water) and I love it so much I can’t go back!
I thought I’d miss that caffeine but it was very easy to give up and I really don’t miss it at all!
Yep, any fleas about the house will jump on to the cat and then die.
No need to decontaminate the entire house, just make sure that fleas can’t make a home on your cat.
