Dear PDSA, a friend’s cat died last year, vets said they think she had anti-freeze poisoning. For more advice go to www.pdsa.org.uk/antifreezeincatsDear PDSA, my dog Coco has always been a bit scared of fireworks, but she coped by hiding in her den with her favourite toy. It sounds like you’ve done all the right things, so I’d recommend giving your vet a call – they can offer help and advice to help Coco through the rest of fireworks season. With consistent training by next Bonfire Night, Coco should have learnt that fireworks are nothing to be scared of!
