So I had a reply from Tesco that said "Thank you for yourr feedback" and went on to say that they were alway
s happy to get feedback from their customers in order to offere a better service. Being somewhat cynical about their altruism I replied that as I was in fact making a complaint and would like an answer to my query.
I used the alternative products - first the so-called lightweight clay which was unmanageable and heavy and followed that with a clumping product. I will spare you the details but imagine a small flat filled with the aroma of cat pee, dust and bits scattered on the floor. Problem: cleaning said dirt-box. Again I will spare you the details but it is enough to say that I spend more time cleaning than actually doing the task.
So I tried the supposed alternative that seems better - a paper based product. The consumer resistance is noticable - Sophie pees and poos on the paper placed under the pan and scrapes disdainfully at the litter.
Sorry to force you to endure the details but I am annoyed by Tescos apparant stupidity in withdrawing what is a popular and useful product that actually works well. Idiots!
I am now thinking of completely abandoning Tescos and going elsewhere for my grocery shopping - like the changing of the gaurd I will be ringing the changes

There are 6 of us cats in our household, and having tried all of them I can recommend Asda's own-brand litter - the one in the purple and cream packs specifically. Mom even goes to asda only to buy this litter, 'cos it's the best one available (better than the really expensive ones too).
I hope this helps.
