Anaesthetists and nurses at veterinary charity Animal Health Trust (AHT) are calling on knitters to help with with a special appeal.

Staff at the AHT’s small animal referral clinic, near Newmarket, Suffolk, have developed a novel way of keeping dogs with long backs warm during the MRI scan, and while they come round from the anaesthetic. The tailored MRI jumpers are made out of knitted squares, as modelled by Ethel (pictured), who is owned by a veterinary nurse.

Kathy Challis, Anaesthesia Nurse at the AHT, says, “Having a supply of knitted squares would be a huge help to keep up the demand for these lovely jumpers which do a very important job in the clinic. So, if you’re looking for a new knitting project, please consider knitting for us.

Kathy continues, “The most useful size squares to help us make these jumpers are approximately 4½ inches by 4½ inches, or about 11 cm square. Alternatively, you can create the desired size by casting on 24 stitches on 4 mm needles and knitting a square. If you can, please choose a yarn that can be washed and dried. The jumper Ethel wears is knitted in garter stitch, but we welcome anything more creative.”

If you are able to help, please post your knitted squares to Kathy Challis, Animal Health Trust, Lanwades Park, Kentford, Suffolk, CB8 7UU or drop off your knitting to either the Visitor Centre or Small Animal Clinic Reception, FAO Kathy Challis. For more information, email
