Good for indoor cats

Perfect for my indoor cat who gets easily bored and stressed. He is much more mellow now. The 2kg bag is a good size to maintain freshness.

Worth a try

by Charlotte Brown -

My vet suggested this for my stressed cat. I've only been using it for a few weeks but I think I see a slight difference. Will continue to use.

Calming cat biscuits

by Emma -

Just wanted to say how all our four cats are enjoying these alongside their wet food and that they have already helped both with a skin condition in one of them and general harmony and relaxation. A really great product, well worth the money. Also, thank very much for the green cat blanket freebie. A very nice gesture and being very much enjoyed! I will be ordering again for sure :o)
