Lovely newish rescue has long fur and accumulates all sorts of seeds etc o. Her daily ventures into our (semi-rural) garden. I brush her daily (which she despises!) but I'm worried what will happen if she ingests all these seeds <may be slightly neurotic >
Basil looks like he was enjoying himself! Another one with a floofy cat here, he's never had problem with swallowing seeds. You might find hairballs are an issue but you can get a paste from the vets called de-furrum (looks and smells like marmite) that fixes the problem. Floofycat loves it, will lick it from the tube
I've got two very fluffy ginger boys who spend hours in the fields and then drag half of the field back with them. Mine are constantly shaking their heads and spitting those tiny little sticky balls out. I find them stuck to everything! I brush my boys as well but I'm sure they ingest a lot of the debris but they have never had any problems.
It doesn't seem to be a problem. Current cat is always covered but he loves being brushed. He also gets slugs stuck to his tummy and pantaloons Old girl didn't seem to get as messy, although she was long haired too, other than when we lived near some horse chestnut trees. The sticky covers that come off the buds in spring used to be plastered all over her and would stick to her tongue when she tried to clean them off! She didn't like brushing and the things were a nightmare to remove, fur full of "glue", bits stuck to the furniture and my clothes!
Get your cat a tangle teaser brush (meant for humans but works on anything with hair). My cat hated being brushed with the cat brush as thing the bristles were too wirey. He loves the tangle teaser though and purrs like an engine when I brush him now
If it's any consolation my MAC got a giant smelly soft poor stuck in her fluffy trouserage today. Wet wipes did not suffice - she had to be held down with a towel and rear end given a trim to get off all the offending scunge. She is currently perfecting her 'I am SO disappointed in you' look.
