MY CAT REACTED VERY BADLY TO THIS LITTER
I normally use the UNscented Professional Classic litter for my twin black girl indoor cats. I liked it for all the reasons mentioned by other reviewers on this site but because the unscented was out of stock, I purchased the scented version instead.
The baby powder scent smelt unpleasantly strong and Bracken and Pippin seemed hesitant at first to enter their covered litter trays with the new litter. But they are very clean little cats and used the litter trays as normal.
Over the next month I noticed both cats vomited a few times - not always hairballs - so this was not normal for them. Pippin gradually grew listless and retiring, choosing to spend time on her own grooming herself instead of wanting to play. Disconcertingly, she started shrinking away when I tried to stroke her.
To cheer Pippin up I brushed her, which she loves. But when she rolled over onto her back I was horrified to find that her undercarriage from tail base to centre of tummy and down the inside of her back legs was totally BALD and PINK instead of black and furry.
The baldness had only occurred since using the scented litter. The pattern and appearance of the baldness, plus her grooming behaviour, suggested that Pippin had been licking (I guessed to remove the scented litter residue from her fur where it came in contact with the litter).
I rushed out immediately and bought a paper-based, unscented litter to replace the Professional Classic scented, thinking to monitor Pips for a couple of days before calling the vet. She seemed much happier pretty much from the word go and stopped over-grooming straight away.
10 days later neither cat has been sick since the new litter was installed. Pippin is back to her playful and affectionate self and her undercarriage has grown an even sheen of new black fur.
The paper based litter works fine from my perspective as cat toilet servant - no odour, easy to clean, very little tracking. My babies happiness, health and wellbeing is paramount. I will never ever buy ANY scented litter again and intend to stick to the unscented, more allergy-friendly ones from now on.
